Updating different tab with a script from a pivot table???? - google-apps-script

Question

I am new to coding scripts in google and come into a problem I can not work through and my script "mentor" is still not that experienced and can't figure it out either.
I am trying to update a different tab on my sheet from a pivot table when I use my script to send out bulked emails.
So the link below will bring you to the dummy sheet built off my real sheet. The 'PM' tab column L is what I am trying to update. It starts at 1 on all jobs. The emails are sent out by the Blue button on the next tab 'Follow up email' (this is just a pivot table so I can always adjust who is getting the emails easily). But I cant figure out how to have it update the 'PM' tab with the button at the same time as the emails go out.
Link to the open shared spreadsheet. Feel free to play around if you can help.

(only got the emails to send properly so far)
function sendEmails() {
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 2; // First row of data to process
var rows = sheet.getLastRow()
var dataRange = sheet.getRange(2, 1, rows-1, 7);
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
var emailAddress = row[1]; // Second column
var message = 'Hello, we have submitted this job ' + row[2] + ' days Ago. ' + row[4] + ' \n\n' + ' -' + row[5];
var subject = row[0]; // First column
MailApp.sendEmail(emailAddress, subject, message);
}
}
I need the button to send out emails on the 'Follow up email' tab and at the same time "email counter" (column L) would get 1 added to it on the 'PM' Tab. This way I can keep track of how many times that job was emailed from the sheet.

Answer 1

Try this code:
function sendEmails() {
var pmSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("PM");
var emailSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Follow up email");
var startRow = 2; // First row of data to process
var rows = emailSheet.getLastRow()
var dataRange = emailSheet.getRange(2, 1, rows-1, 7);
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
var emailAddress = row[1]; // Second column
var message = 'Hello, we have submitted this job ' + row[2] + ' days Ago. ' + row[4] + ' \n\n' + ' -' + row[5];
var subject = row[0]; // First column
MailApp.sendEmail(emailAddress, subject, message);
updatePM(pmSheet, emailAddress);
}
}
function updatePM(sheet, email){
var value;
var emails = sheet.getRange("G3:G" + sheet.getLastRow()).getValues();
for (var i = 0; i < emails.length; i++)
if (emails[i][0] == email){
value = sheet.getRange("K" + (i+3)).getValue() + 1
sheet.getRange("K" + (i+3)).setValue(value);
}
}
I changed the way you got the sheets just to be safe, then I just wrote a small function that gets called after the email is sent, which checks the list of emails in the PM sheet and then updates the value in the sent email column.
