I have a smart list that searches for tag:staples AND status:completed. Basically, when I mark a grocery item completed, I want it moved to a list of staples that I buy all the time - then I can mark it "incomplete" and it will show up on my grocery list again (without recreating the task every time). Make sense?

Anyhow, this works great on the web interface, but not on my iPhone. I can mark the grocery list item "completed" of course, but the smartlist remains empty. This means that I can't make a grocery list on-the-go.

Am I missing something?
