passing public values between objects

I have two game objects. One detects and counts collisions and responds to player action and movement. The other is a simple GUIText object that I want to display the collision counts from the player object. Both have public values for the counts and respond properly if each is tested (Counts accumulate in the player script, I can display values from the GUIText script. How do I pass the values from the player object to the GUIText object? Thanks, Old John
