I am trying to debug the following line of code and am not sure why I am
getting an error as everything looks fine to me. The line is:

If IsError(Application.VLookup(Cells(ProductTitleRow, j),
Workbooks(Current_Consolidated_Units).Sheets(Cells (i,
RegionColumn)).Range("L410:BC418"), Consolidated_Offset + Growth * Cells(i,
GrowthColumn), False)) Then

And the values which come up as I move my mouse over each item a
Cells(ProductTitleRow, j)="APPL/PROF SVC"
Current_Consolidated_Units="2006 Access Based Units - Actuals.xls"
Cells(i, RegionColumn)="QC"
Consolidated_Offset=36
Growth=6
Cells(i, GrowthColumn)=1

I am at a loss in understanding what might be wrong as it looks to me as
though all types within all fields are correct. Can you tell me if you see a
problem. Or is there something else that might be wrong?

Thanks.

Darrell
