I have tried: Code: ' Error Messages ErrMsg11: MsgBox ("This macro is intended for 'DT Global Orders Incomplete.xlsx'" & vbCrLf & _ "Please ensure that is is on error goto named correctly or that you are running the macro on the correct file."), , "Filename Error - You got Schooled!" ErrMsg12: MsgBox ("Enter the main sheet is titled:" & vbCrLf & "'DT Global Orders Incomplete'."), , "Wrong Sheet Titles!" Windows("DT Global Orders Incomplete.xlsx").Activate On Error GoTo ErrMsg11 Sheets("DT Global Orders Incomplete").Select On Error GoTo ErrMsg12 It always flags the errors though even if there is no error happening. I tried putting the labels at the end of my sub but then they're never flagged! Can anyone help me out? Ideally I want a message box to flag up with the message telling someone what they did wrong.
