Thanks for your update, however the fields that are getting this error
on my form are standard fields as per my figures below.As you can notice
I have also turned off the validation script message as well. The only
option I am left with after checking no code was left over in XML that
would cause this, would be to change the form level validation settings
to not give the warning message box at all on the page, which affects
any other validations I would like to work.
