Camerapick Problem

I have problem with the camerapick function.
I wrote this code:
If mousehit(1)
camerapick(camera,mousex(),mousey())
positionentity pgopoint,pickedx#(),-25,pickedz#()
end if
And everywhere i am clicking it's positioning it on 0,-25,0
Why???
(sorry about my english if there is problam with her)
