Well, it *would* be neat, if it could work in Query expressions. I've just been playing around with it and reading the help. It seems it works in forms, reports, macros and modules, but not in query expressions. WTH not? And not only that, when using it in calculated controls on forms, and making reference to other controls on the form, you have to use the entire forms!formname!controlname, instead of simply controlname. Well that's a bit tedious, but I guess at least it works. But I really want it in a calculated expression in a query, so that any form may utilise the value.

I dunno, maybe I haven't used it correctly. I tried 1/[Rate], 1/[tblRates].[Rate]
I was a little puzzled why it wouldn't even accept me!controlname when calculating it on a form.

Any suggestions?
