troubleshoot ActiveSheet.Name

Hello, can anyone out there see a reason the following code would fail? I had the EXACT code in another macro that worked fine. I have gone through this macro line by line and all works well except the second (and probably 2nd to last) lines refering to shtOriginal. What happens is that when I run the macro it will debug with the 2nd line 'shtOriginal' phrase highlighted and the error message 'variable not defined'. The purpose of the second and 2nd to last line is so that after the info is copied and pasted to the '5th worksheet' I want it to then return to WHICHEVER of the worksheets (1-4) the user was last on.

Application.ScreenUpdating = False
shtOriginal = ActiveSheet.Name
ActiveCell.Rows("1:1").EntireRow.Select
Selection.Copy
Sheets("My Class").Select
ActiveCell.Offset(1, 0).Range("A1").Select
ActiveSheet.Paste
With Selection.Font
.Name = "Arial"
.Size = 8
End With
Sheets(shtOriginal).Select
ActiveCell.Offset(1, 1).Activate
Application.ScreenUpdating = True
End Sub

Any ideas? Many thanks if so!

Try this at the top of your code

Dim shtOriginal As String

That did the trick, Mr. Las Vegas!! Thanks a million from Australia
