[Zope] Error Checking in DTML

[lmcdonnell at iwon.com]

  Hi,

 I have a small problem. I wrote and dtml form with several input fields. After hitting the submit button, I pass one of the variables to an sql call to find. If it is a valid record, I will display my information but if the record is invalid, I see a blank screen. 

 I have goolged around and I did not find any clues to my problem. Is there an error type I can look for? Any help would be appreciate, thanks

 Larry
