Calculating dollar Values

[nightdesigns]

I'm trying to calculate dollar totals with fields that are numbers. it's simple, field A + field B = field C. unfortunatly, it chops off any thing after the decimal place if it's a 0. So $15.00 comes out as $15. How do i set it to keep the 2 places after the decimal point.

Go to Format:Number, format it as currency, and have it show two decimal places.
