Do conditional value lists NOT work in IWP?

[Lougee]

My database records curriculum activity for a number of participating schools. When I'm working in my original copy, the conditional value list works just fine, showing only those activities that are related to the chosen topic.

In IWP though, the second list (the conditional list) doesn't even show on the page. I've tried a drop-down list, pop-up menu, checkbox and it still doesn't work.

Is it me? If so, how do I fix this?

I'm using FMA 8.5 on a Mac G5 running OS X 4.8.

Thanks for listening.
