Candybags: Candybags HUD

//Scripts for Candybags by NawtieNitey "NaNi" October 2014
//Revised for Pastebin.com  March 2019

//Rez a prim. Name it "Candybags HUD". Create a note-
//card, and paste the information from "Candybags
//Notecard" into the new notecard. Name the notecard
//"Dialog Button Menu" and place a copy inside the HUD.
//Put some prizes into the HUD. Put this script in it.
//Take the prim/HUD back into inventory and right click
//it. Select "Attach as HUD" and select a spot on your
//screen to place it.

//"Dialog Button Menu" so make sure your HUD has a
