Open form with button , HOW?

[Cyril]

First of all I am using Infopath SP1.
I have a form with a dropdownlist polulated with the names of some other
infopath for m( ex: 1.xml, 2.xml, 3.xml etc...)

I would like to make a selection in the dropdownlist, like 2.xml, then click
on a button and have the selected form open in Infopath.

I am sure this is possible using some king of scripting but I have no idea
how to do it. can someone post the code that would help me do this?

Thanks a lot

Cyril
