An unknown error occurred - simply on submitform!

Hi everyone, an unknown error is occurring on my new submission form, the submit button is on select: SubmitForm(Form1)

It has worked previously and I have no clue why it has decided to stop working. Is there anything I can do to troubleshoot this other than going through every bit of code on the form?

I've resolved this error - one item had nothing in "default" (I recall it was misbehaving a while back), reinserted this field and removed the troublesome one, now working fine.
