Try --
DateDiff("d",Date(),DMax([BillDate])

Your DMAX statement is not correct. I am assuming BillDate is a field in a
table. You need to supply the name of the table and depending on how
BillDate is used, you may need some criteria to limit the lookup. See DMAX
in Access Help for more info.

DateDiff("d",Date(),DMax("[BillDate]", "MyTableNameHere", "Critera = '" &
something & "'"))

ok, tried this, ad it gives the correct answer for just a flash and then
gives me #error

=IIf(Nz(DSum("BillAmt","TTimeBilling","TimeID=Forms!TimeCards!TimeID"),0)=Nz(DSum("Payment","TPaymentSub","TimeID=Forms!TimeCards!TimeID"),0),0,DateDiff("d",Date(),DMax("BillDate","TTimeBilling","TimeID=Forms!TimeCards!TimeID")))
