I apologize if this has already been asked a bunch of times. It looks like other people have various forms of this question but I haven't found an answer that works for me.
I'm trying to put a custom field named person_key into a web link url.
I've tried various forms (12 so far) of the following:
I want to link to my_site.com, subdirectory ws, file name afco_car_kits.php, with a GET parameter of id=xxx,
where xxx is from the person_key custom field in the contact record.
So far, all my efforts have resulted in the correct URL, right up to and including ?id=. The id parameter itself is always blank.
How to I write the link to pick up this custom field? Thanks,
