Error Message when running macro

[Debbie]

I need some help with Access. I'm a new user and am trying to set up a
database for personal use. I'm okay with almost everything except macros. I
keep getting "You cancelled your previous operation"

Here's what I have:

DCount("*","qryMain","[tblPW]=Forms![frmFindPW]![txtPWID]")<=0

DCount("*","qryMain","[tblPW]=Forms![frmFindPW]![txtPWID]")>0

If I enter data in txtPWID on my frmFindPW and that data is not found in
tblPW , I want a msgbox to pop up, but if the data is found in tblPW, then I
want a second form to open. I've got the actions set up properly (I'm pretty
sure), but I always get that same error msg just before the macro runs.
I'm not sure if any of this makes sense to anyone. Is there something that
is incorrect or missing from my condition?

You must provide a field name like:

DCount("*","qryMain","[tblPW].[PWIDField]=Forms![frmFindPW]![txtPWID]")<=0
