I've written the following addon, which scans the auction house to find the total price of vial of the sands mats:

The problem I have is the first time I type /vc it will search for Truegold and the results will be shown, and if I have /eventtrace open I will see AUCTION_ITEM_LIST_UPDATE, but VialCrafter_event() won't be called. If I type /vc again it will work fine.
I have tried with all other addons disabled, and I have also tried moving VialCrafter_Frame:RegisterEvent("AUCTION_ITEM_LIST_UPDATE"); into the OnLoad (in case it's some sort of delay in registering for the event) but nothing has had any effect.
Anybody have any ideas/see any problems in my code? Thank you.
