So far, we've set up the button catching section like this:

     messagebox "What would you like to do?" "Duplicate everything" "Nothing"

     elseif (Choice == 0) ;Duplicate items one by one from the player, into a container

       pContainer.AddItem pInvObj 1

"Duplicate Everything" requires several frames to complete. Once GetButtonPressed returns the player's choice, it will start off and add the first item to the container. However, on the following frames GetButtonPressed will return -1, causing an infinite loop of 'if (Choice == -1) -> return'. To prevent this, only run GetButtonPressed when it had previously returned -1:

     messagebox "What would you like to do?" "Duplicate everything" "Nothing"

     elseif (Choice == 0) ;Duplicate items one by one from the player, into a container

       pContainer.AddItem pInvObj 1

Note that Choice is reset to -1 after displaying a menu. Otherwise, Choice would still be the same as for the last menu (let's say the player choose 0). This would not be -1, so GetButtonPressed would never be run, and that Choice (0) would run instead of the player's choice.
