If your "ready for msgbox" message appears in the Results panel then the msgbox should have opened.  If it didn't open then something strange is happening. Remove the return immediately before the endif (it really shouldn't be there but, in theory anyway shouldn't do any harm) and see if it makes a difference. Mervyn.
