IIf syntax wrong?

I have a checkbox on a report that can either be true or false.

I also have a text field on the report that I'm trying to use the following syntax as it's control source.  But I get an invalid syntax error.

=IIf([chkbxTaxable] = False,0, =[txtSubtotalWithDiscount]*DLookUp("[TaxPercentage]","tblTaxPercentage"))

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

try removing the "=" sign after "0"

=IIf([chkbxTaxable] = False,0, [txtSubtotalWithDiscount]*DLookUp("[TaxPercentage]","tblTaxPercentage"))
