I Cant seem to get a Object to detect A Mouse Click while using A First Person Controller

My Game Use’s the first person Controller and I can’t get to recognize a mouse Click.
If i take the Cube out of my controller it works but if a add to to move with the controller i can’t seem to get it to see a mouse click on my Cube.

here is what i got so far
var Object1 : Transform;
var CHK : boolean = false;

function OnMouseOver()
{
if(Input.GetMouseButtonDown(0)){
CHK=true;
print(“Mouse Button 1 was Clicked”)
}
}
any help would be nice

Ok here is what I did I took a way the rigidbody from the First Person Controller and Bam it now works I dont know wht but it does if any one knows why i would love to lean it but thanks any ways
