trigger not working

I want the user to be able to trigger a web link from inside a session So I have setup cube with a mesh collider, a first person controller, and a script attached to the cube which detect the collision and activate the link with the wwwform The trigger does not work and I cannot find out what I am missing here Is there a component missing or what should be the workflow for that type of interaction? Thanks yves

Use a BoxCollider, not a Mesh Collider:

And sometimes character controller collisions can act strange... add a child game object with a simple Capsule Collider to your character, that only reacts to the trigger (via tags or something like that).
