As this is a Python expression that needs to be evaluated, it cannot be in a string. You can use the "%" operator which takes a format string and an object or tuple as parameters and formats object/tuple according to the string. If your Python method contains a "return result", then there is not magically a "result" variable (and there is not need for it, too). Are you sure, you want the nested "dtml-in". Looks very strange. Thus, you can use: <dtml-in expr="REQUEST.form.items()"> <dtml-var expr="testSQL(text='%sx%s' % (_['sequence-key],_[' sequence-item]))"> </dtml-in> Dieter
