Hi there,
I’ve got the same problem and just resolved it using this code :
on_sent_ok: "var img = new Image(); img.src='####INSERT HERE THE GOOGLE CONVERSION IMAGE SRC####'"
In your case al612 the code will be :
on_sent_ok: "var img = new Image(); img.src='http://www.googleadservices.com/pagead/conversion/989789720/?label=TGu4CNO_n2UQmPz71wM&guid=ON&script=0'"
Make sure it’s ONE-LINE ONLY (no CR in the JS code) when copy-pasting it in CF7 field otherwise it won’t be working !
Hope this will help !
