Here, you break the namespace propagation! As a general rule: If you call a DTML object explicitely (i.e. inside "..."), then *always* use "_.None" (or an object or object tuple) and "_" as the first two positional parameters. Only after these two, use your parameters as keyword parameters. If you do not, you break the namespace propagation (passing the "_" down to your called DTML object). If you use the DTML object outside "..." (or in _[...]), then the DTML magic does automatic propagation. Inside "...", you must do it explicitely. Dieter
