How to find the Last Used Row on Each Sheet

[YellowLabPro]

In this loop, I need to change the focus from the ActiveSheet to the rest of the sheets in the workbook.
I refer to the current sheet, the activesheet w/ the variable oWst.
lLrws is the last row variable, LR(oWst, "A") is the function to find the last row.
Can I still use the function, or do I need to use a variable instead?

[VBA]
Function LR(Ws As Worksheet, Col As Variant) As Long
Application.Volatile
If Not IsNumeric(Col) Then Col = Columns(Col).Column()
LR = Ws.Cells(Rows.Count, Col).End(xlUp).Row
End Function
[/VBA]

[VBA]
Set oWst = ActiveSheet

For Each Ws In Workbooks("TGSProductsAttrib.xls").Worksheets
lLrws = LR(oWst, "A")
For i = 2 To lLrws
If Not IsEmpty(Cells(i, "D").Value) Then
'If IsEmpty(Cells(i, "G").Value) And Not IsEmpty(Cells(i, "D").Value) Then 'Or Not IsEmpty(Cells(i, "E").Value) Or Not IsEmpty(Cells(i, "F").Value) Then
Cells(i, "G").Value = Range("D1").Value & Cells(i, "D").Value & "; "
End If

If Not IsEmpty(Cells(i, "E").Value) Then
Cells(i, "G").Value = Cells(i, "G").Value & Range("E1").Value & Cells(i, "E").Value & "; "
End If

If Not IsEmpty(Cells(i, "F").Value) Then
Cells(i, "G").Value = Cells(i, "G").Value & Range("F1").Value & Cells(i, "F").Value & "; "
End If
Next i
i = 2
Columns("A:G").AutoFit
Next Ws

And- even if I change the Function to
lLrwt = Ws.cells(rows.count, "A").end(xlup).row, which does find the last row, changes are only happening on the ActiveSheet.
So I suppose my next ? is how do I tell the the code to activate the next sheet in the For...Each so the code performs the instructions on that next sheet?

Hi Doug,
You can simply pass WS to the function to get the last row in column A for each sheet, but you need to carefully specify the sheet where you are reading writing your data.
[VBA] For Each Ws In Workbooks("TGSProductsAttrib.xls").Worksheets
lLrws = LR(ws, "A") [/VBA]
