I have a Zclass object called States built with folder and renderable

When I try

<dtml-in States> <dtml-var sequence-item> </dtml-in>

I get Error Type: TypeError Error Value: hasattr, argument 2: expected string, int found

Does anyone know why this is happening?

because you feed it (some method but presumably not dtml-in) int, not strings. But seriously, could you give us some more details about what your code has and preferably a traceback also. That way we might be able to help you better Rik
