call script based on onedit / google sheets

Question

I'm looking to launch a script based on an edit on a specific sheet/cell.

Lets say when Sheet 'Scripts' cell A1 = 'Phone Script'

This function launches:

   var formTitle = 'Phone Script';
   var formID = 'My Form ID';
   var form = FormApp.openById(formID);
   var formUrl = form.getPublishedUrl();
   var htmlApp = HtmlService
   .createHtmlOutput('<script>location.href = "' + formUrl + '"</script>')
   .setSandboxMode(HtmlService.SandboxMode.IFRAME)
   .setTitle(formTitle)
   .setWidth(500) 
   .setHeight(450);
   SpreadsheetApp.getActiveSpreadsheet().show(htmlApp);`

I originally had this assigned to a button but I'd like to move off of that.

Answer 1

 function onEditSend850(e) {
 if(e.range.getA1Notation() !== 'C1' || e.value !== 'Send 850') return;
 emailandsave850()
 }

on edit trigger, when c1 reads Send 850 it will run function emailandsave850
