I am trying to return a simple week number based on the value input on a user
form and place the value in a work sheet column.

I have tried the WeekNum formula but it gives me "Compile Error: Sub or
Function Not defined"

I have the Analysis ToolPak installed.

I am using a "pop-up" calendar to input the date for this field. Would that
cause the problem perhaps????

The Macro posts all the values of the userform to the last row of the spread
sheet. I want a column that simple adds in a week number. Nothing fancy. The
code that gives me the error is as follows:

'Determine the next empty row
NextRow = Range("A" & Rows.Count).End(xlUp).Offset(1).Row

'Transfer Data
Cells(NextRow, 5) = QCMonitor.RevLast.Value
Cells(NextRow, 6) = QCMonitor.RevFirst.Value
Cells(NextRow, 7) = QCMonitor.Dept.Value
Cells(NextRow, 8) = QCMonitor.RevDate.Value
Cells(NextRow, 9) = QCMonitor.AcctNumber.Value

'Input values for house-keeping cells
Cells(NextRow, 1) = 1
Cells(NextRow, 2) = Format(QCMonitor.RevDate.Value, "mmm")
Cells(NextRow, 3) = WeekNum(QCMonitor.RevDate.Value, 1)
Cells(NextRow, 4) = Year(QCMonitor.RevDate.Value)

Everything works but the WeekNum Formula, the answer is probably very
simple, but I have tried numberous other formulas without success.

Ideas anybody?
