Open Mail Merge from button on Access 2003

Hi,

I am new to access and wondering if you could please help me with this
problem that i have.

I have created a mail merge which runs of a query, this is working fine no
problems (yet!)

The problem is that i wish to add a button to a form which when clicked on
will open Word and the mail merge document automaticly, and cant seem to find
out how to do this

I am currently using Office 2003 with Windows XP is that changes anything

Thanks for help in advance
.
