Okay, I'm trying to do something with my UI and sprites. What I've created, are red and green lights, 2d images that indicate on/off. I've created a bank of 14 horizontal sprites that present it like a bank of lights. What I want to happen, is the user can click on a light and it changes a visible image. These lights are acting as page markers.

I've loaded these images into a collection. Using a sprite collision, I can retrieve the index in the collection of the sprite that was clicked. Now, I need to swap out the sprite image to turn the selected light ON, and set the existing light that is on to OFF; which can be any of them.

GreenButtons () is a collection of Sprites
GreenOnButton is an image

I've tried using ;

GreenButtons(Index).image = GreenOnButton

This doesn't seem to work. Although, when I first create the collection, I use this command in this form to set the first light to be on and it worked. So, I don't know it doesn't work later when the correct index value is being returned.

Never mind, I figured it out.

My Select Case condition was a syntax error:

I had;

Select Case Collision
Case 1 - 15

instead of;

Case 1 to 15

that was the problem.
