Have Two variables in a if statment?

im somewhat new to javascript so i need some help please.

error im getting: Unexpected token: &&

Here is what im scripting:

 if (ColgameObject.tag == "Hide")
 {
 //Stopping going through the floor by changing var, wait until they are out to make hid_ready = true
 	if (hidden == false) && (hid_ready == false)
 	{
 		hid_ready = true;
 		hidden = true;
 		 transform.localPosition = Vector3(0, -0.5, 0);
 		//Adding a hiding script
 	}
 }

if (hidden == false && hid_ready == false)
or

if (!hidden && !hid_ready)
