Table problems

[Silvine]

I have keys stored in a bag, and every tick I look in the bag to see what keys I still have. I want to store the key names in a table (previous tick) and then compare them with the keys I have in another table (this tick) and then echo on screen that one or more keys is now gone. I can grab the key info ok from the mud, but ive not worked with tables before so any ideas would be appreciated on how to store and search the tables.

It would be helpful if you posted your trigger for grabbing the key info from the mud.
