myDir isn't defined...?

That depends on what shell $user has.  If $user's shell is bash or ksh,
the syntax you have here looks OK (assuming myDir is defined somewhere
on the ssh CLIENT system, and you simply neglected to show us).

If $user's shell is /bin/sh then "export foo=bar" is not necessarily
going to work; it depends on which /bin/sh the system has.  You're safer
with "foo=bar; export foo".

If $user's shell is csh or tcsh, then you need entirely different syntax.
(And $user needs a swift kick, but that's a different story....)
Something like "setenv myVar $a" should do.  Note the lack of an "=" sign.
