VBA Code does not work in a word document

I have vba code in a word document. I would like to use this
documentwithin the office, but the problem is the code doesn't run for
anyone but myself. When they open the document, the code is not there.
This happens when I email them the documents or if I ptu it on our
server. Is there a setting that needs to be checked in order for the
code rto run?
