Response time <= 5.00 then 1 else 0

Hello,
I'm trying to get the number of days that a call was open, I keep getting 1 instead of the total which should be about "X" for the dates that I'm using.  The ClosedIn5 is what I'm working on.  I have included the fields that it uses.  Thanks!

Formula Fields

if {CallLog.CallStatus}='Closed' and {@Closed Date} in {?Begin Date} to {?End Date} and
