Why is for loop in script creating an extra record

[Digit]

I am in the middle of creating a record producer that creates 1-5 records based on the user selection. When I run the code (see below) and select x number of records, I get the expected number of records, but there is always an additional record created first with blank values. (Ex: User selects one for number_of_build_trackers, but gets 2 records - the correct one plus a blank one)

I assume it has something to do with the for loop logic or the arrays initializing strangely, but I can't figure out how to prevent the 'extra' record from being created along with the correct ones.

    // Create # of build records based on user selection         
    for (var i = 1; i <= producer.number_of_build_trackers; i++) {

        // Set variable values           
        var appService = producer['app_service' + i];
        var buildName = producer['build_name' + i];

        var buildRecord = new GlideRecord('u_build_tracker');
        buildRecord.initialize();

        // Check if build name is provided             
        if (buildName) {
            // If build name is provided, concatenate app service and build name                 
            buildRecord.setValue('u_name', appService.getDisplayValue() + ' ' + buildName);
        } else {
            // If no build name provided, use app service value                 
            buildRecord.setValue('u_name', appService.getDisplayValue());
        }
        // Set other field values             
        buildRecord.setValue('u_tech_review', producer.tech_review);
        buildRecord.setValue('u_managed_service', appService);
        buildRecord.insert();
    }

 I'd sure love some advice on this one!

Then it is already like what Danish mentioned. The Record Producer itself will submit a record + your script will submit 1 or more records. So you will always have one additional record.

You might do an current.setAbortAction + a redirect on your Record Producer.

Thanks for the assistance, @Mark Roethof and @Danish Bhairag2 !!

Per your suggestion, adding this line at the end prevented the 'blank' record being created.

current.setAbortAction(true);

REALLY appreciate the help guys.
