GUIText and Raycasting with google cardboard

Hey I am new to coding and I am having a lot of issues with connecting 2 GUIText boxes to text that i have in an object. The Raycasting is working because the objects change color when the camera scrolls over. basically i just need to connect text from to objects to display "this is a cube" and "this is a Sphere" in C# and inside of the GUIText box.
