[Zope] Using results of SQL in form

6 Feb 2001

      I have a Z SQL Method which returns one row and I want to use the data from 
it in a form (I am going to detault the input fields with the values from 
the SQL).  I thought using the dtml-in tag would be a simple way of doing 
this but am having problems passing the method the parameter.  In the code 
below the line

   Edit Video <dtml-var pCode>

renders pCode into the page but the line

   <dtml-in expr="getVideoSQL(pCode)">

generates a runtime error saying pCode not found.

Can anyone advise me as to what I ma doing wrong?

Regards,
ben
