SAPScript Dunning error

Hi,

I have an error when running dunning notices. A popup box appears informing me that the sapscript form does not exist. This only happens in our Dev environment and not in our QAS environment. There does not appear to be any differences in the config settings between the two systems. So I'm going out here on a limb and thinking it has something to do with the form itself. The forms appear to be the same.

Has anyone come across this type of error before and if so how did you resolve it?

Thanks in advance for any assistance given.
