Function working in Excel 2003 gives an error in 2007

[minjae.sheen]

I'm a newbie in VBA, so I might have made a stupid mistake. The
following function procedure worked fine in Excel 2003 at my workplace
but gives a #NAME error in 2007. I appreciate your help.

Also, please comment if you have any recommendation to simplify or
speed up the procedure. Thanks!!

Function Rent(Startmonth As Integer, CurMonth As Integer, RemMonth As
Integer, DT1 As Integer, DT2 As Integer, LeasePrd1 As Integer,
LeasePrd2 As Integer, CurAmount As Currency, AskAmount As Currency,
Inflation As Currency)

Dim i As Integer

For i = 1 To 10

Select Case CurMonth

Case Is <= (Startmonth + RemMonth): Rent = CurAmount

Case Startmonth + RemMonth + DT1 + 1 To _
Startmonth + RemMonth + DT1 + LeasePrd1
Rent = AskAmount * Inflation

Case Startmonth + RemMonth + DT1 + LeasePrd1 + DT2 + 1 To _
Startmonth + RemMonth + DT1 + LeasePrd1 + DT2 + LeasePrd2
Rent = AskAmount * Inflation

Case Startmonth + RemMonth + DT1 + LeasePrd1 + DT2 * (i + 1) +
LeasePrd2 * i + 1 To _
Startmonth + RemMonth + DT1 + LeasePrd1 + (DT2 + LeasePrd2) *
(i + 1)
Rent = AskAmount * Inflation

End Select

Next i

End Function

Hi,

Is the workbook saved as a .xlsm to enable macros to be stored in the
workbook.
Do you have macros enabled in xl2007.

Cheers
