Sorry to hear you're having trouble with this form. I'm looking into it and I'll let you know shortly.
It appears that somehow (probably through copy and paste) you've inserted a vertical tab character as the last character of your form's header. Due to a bug in our system, an error results. You can fix this by deleting this character from the header. I would suggest placing the cursor at the end of the header text and hitting backspace once. If you have trouble with getting this to work, please follow up by emailing firstname.lastname@example.org (you can address it to me) and I'll follow up with you directly and help you get the document working again.
Please let us know if my suggestion here fixed your problem.
You were right, I copied the text from a powerpoint. Now it works.
My pleasure Ivan. Glad I could help.
Just a follow-up note to say that this bug that you encountered should be fixed in our next release.
All the best,
