How do I create a GUI on collision detection?

[system]

My goal is to have a GUI appear when a collision is detected. I’ve got the collision detection part done, but the GUI doesn’t appear. I’ve gotten GUIs to appear before, so I don’t know exactly what I’m doing wrong. I guess part of my problem has to do with the way I have one function do something when another function returns true. I probably did that wrong, most of my coding experience is in Lua. And this isn’t Lua, so I’m probably doing something wrong there.
Can someone help or explain a better way to have a GUI appear when a collision is detected?

 ` function OnTriggerEnter (other : Collider) {
	return (true);
}

function OnGUI () {
	if OnTriggerEnter = true {
		if (GUI.Button (Rect (10,10,150,100), "I am a button")) {
		print ("You clicked the button!");
		}
	}
}
`

You kind of have the right idea - you just need to track this with a boolean.

var buttonReady : boolean = false; // I don't program in UnityScript so excuse any syntax error.

function OnTriggerEnter (other : Collider) {
	buttonReady = true;
}
 
function OnGUI () {
	if (buttonReady) {
		if (GUI.Button (Rect (10,10,150,100), "I am a button")) {
		print ("You clicked the button!");
		}
	}
}
