Hide Last Row not hiding from form submit - google-apps-script

Question

I am attempting to write a script that on form submit will send two sets of data to two different spreadsheets. The data is derived from one form. It is supposed to copy the most recent entry and then hide the row to prevent duplication. I am finding that on some occasions it is not hiding the last row and multiple copies are being copied. I realize my script is probably not the most efficient, for example, I could not get a range to work!
The sleep utilities were inserted as I thought there may have been a delay in the writing of the form's input to the spreadsheet and the script was running before this was complete.
The script is attached to the form which writes to a Form Responses sheet, this is then split to a company spreadsheet and a customer spreadsheet. Well that is the intention anyway!
function copyRow(){
Utilities.sleep(2000)
var ss = SpreadsheetApp.openById('1_pnsvWtqB4CUivQZE65nFR0AG9zTOgqBVSlPZW4YCUQ'); //Source Form Input
var sheet = ss.getSheetByName('Responses');
var lastrow = ss.getLastRow();
var rowIdx = sheet.getLastRow();
var rowValues = sheet.getRange(lastrow,1,1,74).getValues();
Logger.log(rowValues);
Utilities.sleep(5000)
var destValues = []; //Data to AUSJET
destValues.push(rowValues[0][0],rowValues[0][1],rowValues[0][2],rowValues[0][3],rowValues[0][4],rowValues[0][5],rowValues[0][6],rowValues[0][7]

Answer 1

I am assuming, that as the data is coming from the form so the first column will be 'Timestamp'.
So, I have copied the last row from the source spreadsheet and then compared the value of column A of this last row with the value of column A of the last row of Destination sheet, if both matches then I haven't copied the data...
Only thing that may cause an issue here is if two or more responses are submitted exactly at a same time
Try the following code:
function copyRow(){
Utilities.sleep(2000);
var ss = SpreadsheetApp.openById('1_pnsvWtqB4CUivQZE65nFR0AG9zTOgqBVSlPZW4YCUQ');
var sheet = ss.getSheetByName('Responses');
var lastrow = sheet.getLastRow();
var destValues = sheet.getRange('A'+lastrow+':BU'+lastrow).getValues();
var dest = SpreadsheetApp.openById('1KQ43DJsJY0RpSnFHDcVfgAWLRfLKE6OD28CFkbjpJoU').getSheetByName('Form Responses')
if( dest.getRange(dest.getLastRow(), 1,1,1).getValue().toString() != destValues[0][0].toString() )
dest.getRange(dest.getLastRow()+1,1,1,destValues[0].length).setValues(destValues);
var destValues = sheet.getRange('A'+lastrow+':BH'+lastrow).getValues();
var dest = SpreadsheetApp.openById('1qB4OnKF3-OXFR1kR3jewHgYeslLdmIiE3maQNx0MPbk').getSheetByName('ROAMES')
if( dest.getRange(dest.getLastRow(), 1,1,1).getValue().toString() != destValues[0][0].toString() )
dest.getRange(dest.getLastRow()+1,1,1,destValues[0].length).setValues(destValues);
};
