For example, when I use the code:

<dtml-in SQL.names> <dtml-let vname=sequence-item vvalue="SQL()[0][_['sequence-index']]"> <dtml-var vname>, <dtml-var vvalue><br> </dtml-let> </dtml-in>

I get the error: Error Type: KeyError Error Value: SQL.names Look careful at the error information.

It tells you, that "SQL.names" is the problem. Because, you did not enclose it in "...", it is treated as a variable name (i.e. equivalent to <dtml-in name="SQL.names">) and such a variable does not exist ==> KeyError. What you probably wanted was: <dtml-in "SQL.names"> Note the double quotation marks. In this case, "SQL.names" is not treated as a variable name but as a Python expression. Probably, this will not work, either. There are 2 further problems: 1. "SQL" must probably be called 2. "names" is a method and not an attribute; it must be called, too. Try something like: <dtml-let result=SQL> <!-- will call SQL--> <dtml-in "result.names()"> <dtml-let .... vvalue="result[0][_['sequence-index']]"> .... Dieter
