Need some help with Floris Mod & Steam

Alright, so I have already tried installing Floris Expanded Pack 3 different times to different folders, needless to say, it has not worked once. I downloaded the installer [here] (http://mountandblade.nexusmods.com/download/2903). I just need to know what folder I should be installing it to when it asks me to pick which. I checked which module it was in, and Native was the only avaliable option. So please, WHAT folder to you install Floris to when your Mount&Blade: Warband is on Steam?
