Try
<!--#in sequence --> <td><!--#var pic_key null=""--></td> <td><!--#var "getPic(pic_key)" --></td> <!--#/in -->
You can't nest the <!--#var-->'s. Howard C. Shaw III Programmer/SysAdmin St. Thomas High School

Please excuse my lack of zoping intuition but I hoped someone could help with this problem. I read all the doc's I could find but seem to be missing something. It goes like this... I have a ZSQLMethod that returns some tuples. There is a field in the tuple which I wish to use to lookup an external file and return a jpeg, if available. I've created an external method called 'getPic' which I wish to pass the key field to locate the file with but I can't seem to get at the variable. e.g ---------- <!--#in sequence --> <td><!--#var pic_key null=""--></td> <td><!--#var "getPic( <!--#var pic_key --> )" --></td> <!--#/in --> ----------
This doesn't work for reasons not obvious to me.
I've tried creating a class to handle the records. No go. Basically, the External method can't get at the vars defined on each loop thru the sequence returnd from the SQLMethod.
Any insight would be appreciated.
thanks jb
