On Error Statements

You can use the "On Error" statement to specify which type of error handler to use when a run-time error occurs.

On Error { GoTo [ line | 0 | -1 ] | Resume Next } 

There are 3 choices:
1) On Error GoTo 0 - this interrupts your code with a dialog box. This is the default when no error handler is specified.
2) On Error Resume Next - this ignores all run-time errors. This is not recommended.
3) On Error GoTo LineLabel - this lets you provide a custom error handler.
