You need to put Exit Sub (or Exit Function if you're dealing with a
function) before the code for your error handler:

On Error GoTo Err_Routine

' code

End_Routine:
 Exit sub

Err_Routine:
' code
 Resume End_Routine

Note the use of Resume in the error handler. That ensures that the error is
cleared from the stack.  Any cleanup that's required whether or not the
routine is successful would go into the End_Routine block before the Exit
Sub line.

Please post your actual code and the actual error message. There is nothing in
Access called "mesbox", "call exit lable" is meaningless, and the error
certainly doesn't say that.
