Add the text I show above in onCollide between the curly brackets like this .....
(e) = {text = "Red is eliminated"} Make sure you type it exactly as I show here. Then increase the textScale value to some larger number than what you had. About 3.0 or 4.0 should be about right but you can adjust that to the size that you need.
Try this and see if it works now....
IF you still can't make it work, let me know and I will post a scene for you with the correct script.
