[Typo3] EXT: Flexform Help Needed

[Joshua Preston]

Hey guys,

I need to write a new plugin and it has a selector box using a flexform 
that selects News Categories from the tt_new_cat table.  I have the 
field and flexform generated properly, but none of the news categories 
show up in the list to select from.  I'm guessing that the 
###STORAGE_PID### never gets set.  How do I go about getting it to 
populate these field properly?

Thanks!

Joshua Preston.
