>> What object WITH is referring to in this case? Are you sure that it's the line that generates the error?

The object is recieved as a paramater into the method, I have stepped through and the object is definetely available, fuller code is

WITH toObject
  IF PEMSTATUS(m.toObject,"Width",5)
   .ADDPROPERTY( '_nOriginalWidth', .WIDTH )       && This line errors
  ENDIF
ENDWITH
