Changing False to a value

I have a work sheet

I have a sheet that depending on when a product is delivered it counts how many days are in a pd.

If it is a Saturday product 4-1-09 <-> 4-29-09 there are 4 Saturdays in that time frame.

With the 4 Saturdays I can give credit,

My problem is the false statment, since they don't have a value wont give me the numbers I need.

I kind need a if statement that has more then one false statment
