Use the Simple Notation option. For fixed prices just enter the number

Ok. I finally got the calculations to work. But..... when I save and open in Reader, they don't work. Go back to Pro, they don't work there now either. They also don't show up under the Set Field Order Calculations. To reset them, i have to erase the calculations, save, redo the calculations. Preview the form and everything works — calculations happen and i get a total.

I found this thread http://forums.adobe.com/message/1152890#1152890 about it. Is this bug still going on since 2009?
Ok. Apparently you have to enable reader rights after the form is done. It seems to work now. What a pain.
It shouldn't behave like that.
