Neep Help Quickly Please - Want to Loop through my ArrayCollection

programming flash
1

Hi,
I’m using FlashBuilder 4 and trying to create a dropdownlist that populates a datagrid. The functionality is fine but my data is being chopped up too much. Currently every since “nepName” tag in my XML file is showing up in my dropdownlist (which makes for many duplicates of the same names) and only shows the data associated with that nepName tag. I want each nepName (by name ex. Barnegat Bay National Estuary Program) to display only once in my dropdownlist and populate my datadgrid with ALL the data in the XML file that is associated with that name. I’ve been looking for answers without success for a few weeks now and my deadlines are fast approaching. Please help! My code is below.
