retrieving Access data to display in an Infopath form

[MartyMart]

Hello,

I'm kinda new with database and infopath and I have some difficulties to
figure out this:

I have a repeat table with a pull down menu. And I have also an Access
database with 2 columns ' Name' and 'description' So far I can connect my
access database to display the 'Name' in the pull down menu. But now I want
to display the 'Description' on a adjacent expression box when you select his
relative name.

How can I do that? I'm pretty sure it is really simple.. but I'm still a
newb with that!

thanks!
