For example, what "As..." method[s] are you using to refer to parameters? For a Double used as currency you would need AsCurrency, which IBO would convert internally to a 2-place decimal. If you're just using its Value property, any decimal part will have many more places of decimal than just the two in your display mask.

Or what casting you might be doing somewhere in your code to convert Double to 2 places of decimal to fit your mask?

If you set the Currency attribute on the field in ColumnAttributes then it should show in the DFM and IBO would perform the conversion itself as required.

Sorry, missed that. Same problem with those.
