Testing first person controller (mobile) and can't get the collisions to work

So I am developing a first person project for Ipad. I'm using a stardard keyboard and mouse First Person Controller in my levels to get the programming and collision bugs worked out because you can't test the ipad controls directly in Unity. My belief was that I could swap out my scripts to the mobile firstperson controller and that it would work fine in my xcode test. But at the moment the FPC isn't detecting the collisions with the important objects in my scene. Anyone know what step I'm missing?
