Unfortunately, this did not work with my custom code. Here is my code:
<script type="text/javascript">
window.onload=function(){document.getElementById('my_field_id').value = location.href;}
</script>
Maybe I don't have the right field ID?
I sent you an email, I asked over the chat and I will try the Appsumo question, now.
Thank you very much for your help.
Bye
