Try <dtml-if expr="A == B">
Would this make a difference? Python normally doesn't care about this whitespace, IIRC.

But DTML is dangerous.
Sometimes, you do not get the objects you expect. I expect that this is your true problem.
Most times I ran into a problem like this, it was because I had inadvertently converted one or both of the variables to a string (e.g. attempted to pass an integer through a web request instead of a direct call -- I often confused the action of calling a method with an HTTP POST with calling it from another method in Zope, despite the fact that these are actually quite different things). Often, doing something like: <dtml-if expr="_.int(A)==_.int(B)"> Conditional stuff. </dtml-if> would fix it. Don't forget the pesky "_" namespace qualification for builtins in DTML.
