why does this problem appear?

public var gameObject;ActivateTrigger;
if (Input.GetKey(KeyCode.E));
transform.Translate(Vector3(0, 2, 0) * Time.deltaTime);
;
if (Input.GetKey(KeyCode.c));
transform.Translate(-Vector3(0, 2 ,0)

it says this Assets/up and down script.js(1,23): BCE0034: Expressions in statements must only be executed for their side-effects.

Well, turning ActivateTrigger; into ActivateTrigger(); might solve one thing, but if you want help you should maybe post your code properly?
