Craig,

When I execute the code, the debugger stops, highlighting
"Charlestown".  The error was: "Compile Error: Variable Not Defined."

The variable Charlestown must be declared, usually via Dim, before
being used.

If Charlestown is a string, it must be enclosed in "".

Sub Suburb()
 Dim Suburb As String
 Suburb = "Charlestown"
 MsgBox Suburb
End Sub

The above code will execute, and a MsgBox appears with the word
"Charlestown" in it.

Sincerely,

Chris O.
