>I am Set a Default path based on user input. What is the best way to handel the rest of my code when a user puts in bogas info? How can I get On Error to skip the rest of my code(button click code).

You can use DIRECTORY() function to check if the path exists.

* Get User input
lcPath = .....

IF NOT DIRECTORY(lcPath) 
  Messagebox("Bad Path!", 16)
  RETURN
ENDIF

SET DEFA TO ( lcPath )
...

ENDPROC
