[FlashCS3 AS2] listing mcs help!

What im trying to acomplish is to list some mcs by pressing buttons. I got 5 buttons and 5 mcs. If the user press for example 3 buttons the objective is to list that 3 selections in same selection order and if the user deletes the 2nd of the 3 selections the 3rd selection takes the place of the 2nd selection (a population list). I attached a link to the source file. Ive been searching a lot but everything about flash list tutorials is related to the list component and i dont need that so if someone can help it will be highly appreciated. Sorry about bad english :thumb2:
