Is there a Null Zero in Crystal Reports?

Does CR have a NZ Function similar to Access where I can say if a field is a 0 I want to put an empty space.

This is the code I am using:

If{PRTH.EarnCode} = 115 Then {PRTH.Hours} Else 0

Which gives me this:

I want to get this:

Right click and edit format of the formula after its placed on the report in the designer. Then in the customize options select suppress if zero.

Perfect Thank you.
