Google Script not Finishing Successfully - google-apps-script

Question

I recently adapted a short piece of script to automatically send an e-mail to me when a specific response appears (the word FAIL) in a 'Google docs' spreadsheet, that collects responses from volunteers using a 'Google Form' to record their weekly checks on life-saving equipment.
The email on FAIL is working well, having tested it with a few FAIL responses. However, as the form 'owner' I am receiving notifications from Google, for each normal PASS response submitted, telling me that the script failed to finish successfully.
8/4/15 10:57 AM
SendGoogleForm
ReferenceError: "found" is not defined. (line 35, file "Code")
formSubmit
It finishes successfully if a FAIL response is submitted, so I suspect that, due to my inexperience with scripts, I have not defined what should happen when found is 'not true'.
It's probably glaringly obvious to a more experienced script writer but none of the things I have tried with 'Else' seem to work.
Any suggestions would be greatly appreciated.
function Initialize() {
var triggers = ScriptApp.getProjectTriggers();
for (var i in triggers)
ScriptApp.deleteTrigger(triggers[i]);
ScriptApp.newTrigger("SendGoogleForm")
.forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
.onFormSubmit().create();
}
function SendGoogleForm(e) {
if (MailApp.getRemainingDailyQuota() < 1) return;
// Recipients email address
var email = "12345#abcde.co.uk";
// Subject for Google Form email notification
var subject = "Weekly Checks - FAIL Submitted";
var s = SpreadsheetApp.getActiveSheet();
var columns = s.getRange(1, 1, 1, s.getLastColumn()).getValues()[0];
var message = "A check form has been submitted containing a ** FAIL ** response: ";
// Look for a 'FAIL' response
var key = columns[keys];
for ( var keys in columns ) {
if ( e.namedValues[columns[keys]] == 'FAIL') {
found = true;
}
}
// Only include form fields that are not blank
if (found)
for (var keys in columns) {
var key = columns[keys];
if (e.namedValues[key] && (e.namedValues[key] !== "")) {
message += key + ' : ' + e.namedValues[key] + "\n\n";
}
}
MailApp.sendEmail(email, subject, message);
}

Answer 1

Your found variable is null whenever a non-"FAIL" occurs in your script and I think your if(found) is creating the error message.
You could Initialise your variable:
var found = false;
before you start testing it. That way, your if(found) will be false and it will skip down to your send email code.

Answer 2

Perhaps u can use
if ( e.namedValues["Pass or Fail"] == "Fail" ) { ... }
where "Pass or Fail" is the form question title. And also use e.range.getRow() to capture the sheet row that the responses were written.
