When you say you get the same results when reversing the formula, what actually happens? Does one particular module still stubbornly refuse to display, or do you find that whichever one is in the "else" part of the statement does not display?

If it's just 1 of the modules which you can't get to show, try assigning that to a page directly, just to make sure the module itself is ok. Also check on whether it's enabled or not, and if not, then check the "auto-enable included modules" setting in MetaMod.

Did you remember to swap 101 and 102 for the actual module ids you want to display?

Still no joy? Can you post the exact recipes (both exact and "reversed" as you stated above) with an explanation of what happens each time.

Also try turning on debugging mode and see if that gives you any info.

Cheers,
Stephen
