@birdman thanks for these instructions - super helpful. However I can’t seem to get it working. I’m stuck at the same point as CamiG - creating the LookUp table. I’ve created the LT variable as you described but think the Input Variable value might be wrong?
@CamiG did using the value {{Form ID}} work for you? Or did you need to create a new value/variable specifically for HS form IDs? When I go to preview mode in GTM I can’t see the event firing on form submission.
