Changing a Variable within the same script

Hey there i am attempting to create a system where clicking another in-game object will have the camera target that object , the targeting system has already been set up but i need to know how i would go about telling the script to change that variable to target the new object , i 've already set up a Raycast system that checks for the tag of the object each object has the same tag "Cell" , all i need to know is how i can tell the system to change the target to the name of the object my ray cast picks up.

RaycastHit vHit = new RaycastHit(); Ray vRay = Camera.main.ScreenPointToRay(Input.mousePosition); if (vHit.transform.gameObject.tag == "Cell" && Input.GetMouseButtonDown(1)) {

     }

Thanks for your time and patience.
