Newbie Question
I am guessing this is any easy question for most people here but I can't figure out what I am missing and I've spent quite a while trying to figure it out.
I have a script that is supposed to time stamp different columns. All the if functions work correctly for stamping columns A, E, and F by placing input in columns in B, C, and G respectively.
The one issue I having is getting column E to show input when column d is checked. I've tried a number of different ways(which are commented out in the code.)
I am not sure what I am missing but the difference between the code that is working and the code that isn't is that code that is working uses an offset function to place a date stamp of the current time while the code that isn't working is supposed to copy the data from one row up and two columns over. Essentially this means in an example that when column D10 is checked it should copy the time value in F9 to E10(I have corrected this example since my original post. I was a bit tired when I first wrote it)
Here is the example of my code. I have also attached a picture of the spreadsheet for clarity. I suspect the issue that I using a function wrong but I don't have enough experience to understand why.
function onEdit(e){
//CORE VARIABLES
// The columns that trigger datestamps in other columns
var COLUMNB = 2;
var COLUMNC = 3;
var COLUMND = 4;
var COLUMNG = 7;
// Where you want the date time stamp offset from the input location. [row, column]
// DTL = Date Time Location
//Intiates a series of variables to hold the offset values for datestamping the row entry
//Instiates a variable which controls the offset values for column B name entry
//The date stamp currently corresponds to column A and is triggered by selecting a client in column B
var DTLColB = [0,-1];
//Intiates a variable to hold the offset values for datestamping the start time column with the current time
//The date stamp currently corresponds to the time value in column E and the trigger is in column C
var DTLColCCTstart = [0, 2];
//Intiates a variable to hold the offset values for datestamping the start time column with the previous row entry time
//The date stamp currently corresponds to the time value in column E(offset(-1,2))and the trigger is in column D,-,-
//It copies the previous end time into the current start time
var DTLColDLTstart = [0, 1];
//Intiates a variable to hold the offset values for datestamping the current time in the end time col for for a row
//The date stamp currently corresponds to the time value in column F and the trigger is in column G
var DTLColGCTend = [0, -1];
var LastStampCoord = [-1, 2];
//Intiates a variable that controls which sheets this function is active on
var SHEETNAME = 'Cont Log'
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
//checks that we're on the correct sheet.
if( sheet.getSheetName() == SHEETNAME ) {
var selectedCell = ss.getActiveCell();
//checks the column to ensure it is on the one we want to cause the date to appear.
if( selectedCell.getColumn() == COLUMNB) {
var dateTimeCellB = selectedCell.offset(DTLColB[0],DTLColB[1]);
dateTimeCellB.setValue(new Date());
}
if( selectedCell.getColumn() == COLUMNC || selectedCell.getColumn == true ) {
var dateTimeCellC = selectedCell.offset(DTLColCCTstart[0],DTLColCCTstart[1]);
dateTimeCellC.setValue(new Date());
}
if( selectedCell.getColumn() == COLUMND || selectedCell.getColumn == true) {
var dateTimeCellD = selectedCell.offset(DTLColDLTstart[0],DTLColDLTstart[1]);
// var oldtimevalue = selectedCell.offset(LastStampCoord[0],LastStampCoord[1]);
// var oldtimevalue = range.selectedCell.offset(LastStampCoord[0],LastStampCoord[1]));
//var oldtimevalue = selectedCell.offset(LastStampCoord[0],LastStampCoord[1]);
//var oldtimevalue = selectedCell.getrange(selectedCell.offset(LastStampCoord[0], LastStampCoord[1])).getvalues;
//var oldtimerecord = sheet.getrange(selectedCell.offset(LastStampCoord[0],LastStampCoord[1])).getvalue();
//var oldtimevalue = oldtimerecord.getvalue();
// var LastStampLookup = selectedCell.offset(LastStampCoord[0],LastStampCoord[1]).getvalue();
// var LastStampTime = LastStampLookup.getvalue()
// range1.offset(2, 0).setValue("Order complete");
// dateTimeCellD.offset(LastStampCoord[0], LastStampCoord[1]).setvalue(timelocation);
//dateTimeCellD.setValue(new oldtimevalue.getvalue());
dateTimeCellD.setValue(new date());
}
if( selectedCell.getColumn() == COLUMNG || selectedCell.getColumn == true) {
var dateTimeCellG = selectedCell.offset(DTLColGCTend[0],DTLColGCTend[1]);
dateTimeCellG.setValue(new Date());
}
}
}

Answer 1

I am not sure what I am missing but the difference between the code
that is working and the code that isn't
You have a small typing mistake - change
dateTimeCellD.setValue(new date());
to
dateTimeCellD.setValue(new Date());
However, if your goal is to set the value of dateTimeCellD to the one of the cell 1 to the right, one to the top - you can do it with
dateTimeCellD.setValue(dateTimeCellD.offset(-1,1).getValue());
See the method descriptions here and here.

Answer 2

Try this:
function onEdit(e){
var sh=e.range.getSheet();
if( sh.getName()=="Cont Log" ) {
var ts=Utilities.formatDate(new Date(),Session.getScriptTimeZone(),"E MM/dd/yyyy HH:mm:ss");
if(e.range.columnStart==2) {e.range.offset(0,-1).setValue(ts);}
if(e.range.columnStart==3) {e.range.offset(0,2).setValue(ts);}
if(e.range.columnStart==4) {e.range.offset(0,1).setValue(ts);}
if(e.range.columnStart==7) {e.range.offset(0,-1).setValue(ts);}
}
}
