Hud Button Touch Detach (add)

I was looking for a script I can add to one button who is linked to the HUD, But Unfortunately the Script only work if you put it into the main prim and not into a Button as the Description seam to say. should be more cleare. I was looking for a detach script to avoid a ''detach'' HUD by mistake when the people want select one option. but it work fine if you add it to the main prim HUD. For the not clear info I will give a 3 stars. Have nice day
