Changing a value from the SmoothFollow script OnCollisionEnter

I have a little racing game and in the first part i am driving in a tunnel so the value height from the SmoothFollow Script is equals 1.
With the OnCollisionEnter function i want that if i reach this cube with the tag CamChange the value height changes to 5.

function OnCollisonEnter(hit : Collider)
{

if(hit==GameObject.FindWithTag("CamChange"))

 {

 cam1.GetComponent("SmoothFollow").
  }
  
}

thats what i habe until now after the dot i dont know what to mention
help would be pretty nice :slight_smile:

cam1.GetComponent(“SmoothFollow”).height = 5.0;
