Toolbar Selection

Hello, I was making my character selection screen but got stuck on a probably stupid problem. The thing is that I want to be able to click one of the options, either Assassin, Mage, or Tank and then have a GuiText appear. I have the GuiText ready, but I just have to find out how to make the toolbar toggle it. Here is my code. var originalWidth = 640.0; // define here the original resolution var originalHeight = 400.0; // you used to create the GUI contents var toolbarInt = 3; var toolbarStrings : String[] = ["Assassin", "Tank", "Mage"];

 private var scale: Vector3;
 
 function OnGUI(){
     scale.x = Screen.width/originalWidth; // calculate hor scale
     scale.y = Screen.height/originalHeight; // calculate vert scale
     scale.z = 1;
     var svMat = GUI.matrix; // save current matrix
     toolbarInt = GUI.Toolbar (Rect (450, 25, 400, 50), toolbarInt, toolbarStrings);    
 }
