Formcalc: Calculate number of days between dates

Hi all,

I'm trying to set up a field that will show the number of days between a user-entered date and a current/today's date field. 

I tried to adapt a script from another post, but I'm not getting it to work.

form1.sf1.CCSub.CCGroup.#subform[0].DateField2::exit - (FormCalc, client)

form1.sf1.CCSub.CCGroup.#subform[0].NumericField2.rawValue = Date2Num(DateField1, "MM-DD-YY") - Date2Num(DateField2, "MM-DD-YY")

and here's my file:

any help would sure be appreciated!

Thanks!
