One mandatory field reports no data when populated

One mandatory field reports no data when populated

Hi,

I have a simple data entry form that allows entry of around
8 different fields.

When using Firefox (2.0.0.14) one of the mandatory fields (venue)
consistently reports an error when trying to submit, saying a value
must be entered, even though a perfectly valid value has been entered OK.

Other users of the form have reported the same issue.

Seems OK in AOL (IE7). Is there a known Firefox issue?

Please advise if you need more info.

Also had problems with the security code not being accepted
so have disabled this for now. Any known issues there?

Thanks a lot!
Dave
