[Zope] DTML and ZSQL help

[Tuttle, Gene]

 am having a problem accessing a ZSQL method that is not in the acquisition
path.
When try the following I get an error


<dtml-in "/SAS/queries/add_customer(REQUEST)">

Expression (Python) Syntax error: 
invalid syntax
, for tag <dtml-in "/SAS/queries/add_customer(REQUEST)">, on line 23 of
index_html 

is there a way to do this?

Thanks
Gene Tuttle
