Hi,
Perhaps something like this may help.
Code:
Sub test()
Application.ScreenUpdating = False
Dim myrng As Range
For Each myrng In Sheets("Sheet1").Range("F2:F" & Sheets("Sheet1").Range("F65536").End(xlUp).Row)
If Sheets("Sheet1").Cells(myrng.Row, 6).Text = "TOOL ASSEMBLY" Then
MsgBox "Tool Assembly"
Sheets("Sheet1").Cells(myrng.Row, 1).Value = "Test"
Sheets("Sheet1").Cells(myrng.Row, 2).Value = "Test1"
Sheets("Sheet1").Cells(myrng.Row, 3).Value = "Test2"
Sheets("Sheet1").Cells(myrng.Row, 4).Value = "Test3"
End If
Next
End Sub
