Error: Expected End of Statement

I just don't see it (SSRS 2005 Expression Syntax Error):

=((Fields!PostedAmount_InHouse.Value + Fields!NewPDs_Check.Value + Fields!NewCCs_Check.Value) / Fields!CurrentPostingDay.Value) * (Fields!TotalPostingDays.Value - Fields!CurrentPostingDay.Value) + (Fields!PostedAmount_InHouse.Value + Fields!OldPDs_Check.Value + Fields!NewPDs_Check.Value + Fields!OldCCs_Check.Value + Fields!NewCCs_Check.Value) * Fields!FeeSchedule.Value)) / 100

Error: Expected End of Statement

4( + 6) = Error: Expected Endof Statement
