Autofilter last column

[jomili]

My current code is:

 ActiveSheet.UsedRange.AutoFilter Field:=16, _
            Criteria1:="0", _
            Operator:=xlOr, _
            Criteria2:="(0)"

However, I'm working with multiple sheets, and column 16 isn't always the column I want to filter, but it's always the last column I want to filter. How would I change my code to do that?

Thanks,
John
