GUI to follow 3d instantiated object in other camera?

Hi Guys, having trouble getting a 2d math equation to show up in a secondary camera layer. The instantiated PowerUp object shows in the second layer, but the GUI, though a child object, appears in the camera.main. I’m using the same script to generate equations for the asteroid equations and the PowerUP equations, using a conditional to separate them out. Should I use and array of cameras for different GUI? Can I get a reference to a second camera on the fly like Camera.main ??? Not sure. Appreciate your brilliance and generosity.

if(m_quientGT)
		{
			m_quientGT.transform.position = Camera.main.WorldToViewportPoint(transform.position+quientOffset);

			if (this.gameObject.tag == "PowerUp")
			{	  

				m_quientGT.transform.position = Camera.????????????.WorldToViewportPoint(transform.position+quientOffset);
			}
		}

There are lots of ways to accomplish this goal. You don’t say what language. I’ll assume Javascript/Unityscript:

At the top of the file:

private var secondCamera : Camera;

In Start():

   secondCamera = GameObject.Find("SecondCameraName").camera;

In your code above:

m_quientGT.transform.position = scecondCamera.WorldToViewportPoint(transform.position+quientOffset);

As a bit less efficient alternate, give your camera a unique tag then you can do:

 m_quientGT.transform.position = GameObject.FindWithTag("SecondCameraTag").camera.WorldToViewportPoint(transform.position+quientOffset);
