i have this problem: it is not possible to invoke an expression of type 'int'

the aim of the sript is to reduce the light intensity of the main light and at the same time to increase the intensity of the other.

 var other : Light = GetComponent(Light);
    var other2 : Light = GetComponent (Light);
    
    
    
    function Start () {
    
    }
    
    function Update () {
    
    other2.intensity = 30(0.2 - other.intensity);
    
    if(other.intensity > 0.2){
    other.intensity = 0.2;
    }
    
    if (Input.GetKey(KeyCode.Q)){
    otro.intensity = 0;
    
    
    }
    
    if (Input.GetKey(KeyCode.R)){
    other.intensity = 0.2;
    
    }
    if (Input.GetKey(KeyCode.E)){
    other.intensity += 0.01;
    
    
    
    }
    
    
    if (Input.GetKey(KeyCode.W)){
    otro.intensity -= 0.01;
    
    
    
    }
    
    
    
    
    }

Mono develop says the problem is here:

other2.intensity = 30(0.2 - other.intensity);

thx for helping

Yep, 30(…) tries to make 30 a function, just need a *

other2.intensity = 30*(0.2 - other.intensity);
