[Zope] What is the Python script that is similar to a dtml-in call

[Larry McDonnell]

Hi,

I need some advice. I still use dtml calls in my systems. My problem is 
if the user is searching for a record but the record is not found. The 
call is as follows:

<dtml-call "REQUEST.set('serial_number', serial_number)">

<dtml-in lookup_header_record>
  <dtml-call "REQUEST.set('equip_type', equip_type)">
  <dtml-call "REQUEST.set('pr', pr)">
</dtml-in>

If the record is not found I get this error:

Error Type: KeyError
Error Value: equip_type

True statement since there is not record and further in the form I am 
trying to output this variable.
Are there any examples that either traps for an error or python script 
that can also lookup the record and true a found/not found status.

Thanks,
Larry
