// Rollover Button code

//

// This code automatically generates the rollover code necessary for each menu item.

// In addition, the code figures out which button is in the pressed state, and 

// Doesn't roll the button over if it is. 

// For imformation on how to use this code, please read "RollOver-Documentation.txt".





// ________Menu Creation (MODIFIABLE)______________________________________________________________



// ________Constants_______________

//  Button Image Sizes

var BUTTON_WIDTH = 192, BUTTON_HEIGHT = 24;





//  Paths

var buttonPath_ForwardSlash = "graphics/subpage/";  // Must include '/' at the end of the path

var buttonPath_BackSlash = "graphics\\subpage\\";   // Must include '\\' at the end of the path

								// Use '\\' for a backSlash 

								// This is only used for searching 

//  Subpaths

var normalButtonSubPath = "normal";  // If using the "buttonPaths for one of the subpaths, set it to: ""

var hoverButtonSubPath= "pressed";

var pressedButtonSubPath = "pressed";   // NOTE: you need to specify BOTH hover and pressed



//  Names of the buttons

//  Must be the same as the "name" parameters in the anchor tags for the menu buttons.

var buttonNames = new Array("home","about","program","advantage","schedule","faq","gallery","contact");
