Specifying form for 'on form submit' trigger

Question

I have two google forms, which send data to two tabs in a single spreadsheet.

I have set up a script with two functions. I would like the first function to run on s

Another way this can be done is by looking at the sheet name that comes in the response's event object via the range property. Here's an example of how I determined the form that triggered the submission:

// set the sheet name that stores the form responses you care about here:
function getSourceSheetName() { return 'Form Responses 1'; }

function submit(eventObj) {
    var range = eventObj.range;

    var eventSourceSheetName = range.getSheet().getName();
    var givenSourceSheetName = getSourceSheetName();

    // if the source sheet (from form response sheet) is not the same as the specified form response sheet, quit (return) so extra forms don't trigger the code
    if (eventSourceSheetName.toUpperCase() !== givenSourceSheetName.toUpperCase() ) {
        Logger.log('A different form just submitted data - quit code');
        return;
    }

    // you now know which form submitted the response, so do whatever you want!
    // ... your code goes here
}

Basically, this code grabs the name of the sheet that the Form response comes from via range.getSheet().getName(). Next, it checks if that name is a specified name we're looking for (specified in the function getSourceSheetName().

I think it's also possible to get the active sheet name via:

eventObj.source.getActiveSheet().getName();

In case you don't want to use "Range".

I hope this helps!
