I just installed this addon last night. I am trying to use the custom filter (Panda cooking items not listed) but I am not having any luck. Is there a help file somewhere?

no, there's not really a help file anywhere. Can you post a screenshot of the custom filter as you have it setup. And a link to the item you are trying to use in the custom filter.

https://www.wowhead.com/item=74843/scallions is the item I'm trying to add (there will be others as none of the veggie items are listed)

Ok, cancel that... I was using the wrong ID. Sorry, I've never used ID before. :((

yeah, I was about to explain that.
