>When placed in a test form it works fine. However, if I close the form and try to run it again it returns an error from the MAPI controller (usually it can't find the attachment). If I quit FoxPro and start it again, the same code works again. Any idea what I'm doing wrong?

There might be a problem with the default directory. Find out if its being changed automatially by the MAPI controls by testing Curdir() before and after you run teh program.
