That's not going to work. Unlike Python, DTML doesn't seem to like using a variable in an expression whose output is stored in the same variable.

I do not believe this: "REQUEST.set" is a normal Python function. Calling it, first evaluates the arguments and only then enters the function body. However, I remember faintly, that there was a DTML namespace caching issue. Under some circumstances the value read from "REQUEST" was cached and later delivered from the cache rather than freshly read from "REQUEST". Dieter
