Hi, I am modifying an existing marketing event registration form to include custom event registration fields. I have:
- created and activated the custom registration fields
- added the custom registration fields to the event(s)
- created a form using 'standard fields' and run error checking on it, it is fine.
The problem occurs when I try and add the custom registration fields to the form. I am able to add a custom registration field from the list in the toolbox. However when I 'check for errors' I get the following error:

this error prevents me from 'going live' with the form.
The error occurs regardless of which custom field I add.

Can anyone please advise how to resolve this issue? Thanks.
