Populating a list items dynamically can cause cascades of reentrant event. So be careful.

thanks, i will look into it.

i found an example where text is inserted in a list and then thru a button exported into a droplist..

hopefully i can reverse that.

The last article in my list is about adding new list items to a dropdown from changes in another dropdown. 

Should be close to what you need.

It has an example PDF that moves items from one list to another. 

It has everything you need to figure you how to write the script you want.
