Dwindling Portal to Portal selection

Hi all,

I've been trying to put together a portal that shows all available options, which can be 'selected' (creating a many-to-many join). The selected options would be shown in a second portal, and removed from the first.

I found this reference:

http://fmforums.com/forum/topic/48666-matching-values-in-separate-repeating-fields/page__p__227334#entry227334

In which Comment posts an example (1166915248-PortalToPortal.fp7.zip) that does exactly what I want, except for one problem: if there are no selections ("Installed Software" in Comment's demo), there are no available options. Works perfectly except for that.

How can I get it to show all available options without first having something 'installed'? I'm pretty sure the problem has to do with the value list not existing until something is 'installed' but I can't think of a workaround.

Thanks.
