function onEdit() runs only partially - google-apps-script

Question

I have a very frustrating problem on my hands and I turn to you for help once more. I had the onEdit() function below which, together with the auxiliary functions, worked fine.
function onEdit() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var activeSheet = ss.getActiveSheet();
var activeCell = activeSheet.getActiveCell();
//Check if the sheet is a JOb sheet and the cell us the status cell
if ( activeSheet.getName().indexOf("Job ID") != -1 && activeCell.getRow() == 4 && activeCell.getColumn() == 15 ) {
var targetSheet = ss.getSheetByName('Active Jobs');
var jobRowNumber = findJobIdRow();
var sourceCell = activeSheet.getRange(4,15);
sourceCell.copyTo(targetSheet.getRange(jobRowNumber,16));
}
if (activeSheet.getName().indexOf("Job ID") != -1 && activeCell.getRow() == 2 && activeCell.getColumn() == 15){
var switchValue = activeCell.getValue();
switch (switchValue){
case "On hold (i)":
case "On hold (ii)":
case "On hold (iii)":
case "To be assigned":
//Write date to active jobs sheet
addDateToActive("TBC");
break;
case "In progress":
var newDate = Browser.inputBox("Please enter report out date, example 18-Aug-2017");
addDateToActive(newDate);
break;
//default:
//Browser.msgBox("GOTHERE");
}
}
}
function findJobIdRow() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var jobID = ss.getActiveSheet().getRange(2,1).getValue();
var column = ss.getSheetByName('Active Jobs').getRange(2,1,ss.getSheetByName('Active Jobs').getMaxRows()-2,1);
var values = column.getValues(); // get all data in one call
for(var ct = 0; ct < values.length-1; ct++){
if(values[ct][0] == jobID){
var ct = ct+2;
break;
}
}
return ct;
}
function addDateToActive(input){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var activeSheet = ss.getActiveSheet();
var activeCell = activeSheet.getActiveCell();
var jobid = activeSheet.getRange(2,1).getValue().toString();
var activeJobSheet = ss.getSheetByName("Active Jobs");
var activeJobs = activeJobSheet.getRange(1,1,activeJobSheet.getLastRow(),1).getValues();
activeJobs = ColumnToArray(activeJobs);
var jobrow = activeJobs.indexOf(jobid)+1;
if (jobrow == -1){
Browser.msgBox("Job Id not preent on Active Jobs sheet");
}else{
activeJobSheet.getRange(jobrow,15).setValue(input);
}
}
Then I included some code in this script which was supposed to send out some e-mails to people if some dates were approaching today's date. There were some problems with that code because of authorization requirement so I moved it into it's own separate function and came back to the original script that is posted above. Now the problem I am facing is, although this script works fine if ran from the script editor, manually run from a drawing button in the spreadsheet, or is ran by a on edit trigger I set up from the "Current project triggers" menu, it will not do the entire script if the script is triggered by the onEdit() function name. It does the first bit where it copies the content of a cell across but not the second bit with the case switch.
The obvious fix would be to just set up the trigger from the "Current project triggers" but this onEdit detection needs to apply to anyone in my team that edits this sheet. If I set it up like that it will work for me but no one else from my team.
Any help would be appreciated.

Answer 1

Setting up the trigger via the function name onEdit() proving tricky I wrote this bit of code and attached it to a drawing in the sheet. Then instructed all the users to click it which set up the trigger for them. This solved the problem and the trigger works fine now.
function triggerSetUp(){
var sheet = SpreadsheetApp.getActive();
ScriptApp.newTrigger("enforcer").forSpreadsheet(sheet).onEdit().create();
}
