Lua error when logging into a toon TBCC

I get the following error whenever I log into a toon on TBCC

Mail.lua.gz this is my mail.lua, still not finished but I dont get any errors... maybe its related to an addon which modifies your mailbox?

just copy it to _classic_\Interface\AddOns\AddOnSkins\Skins\TBC\Blizzard

That seems to work fine. I use TSM btw which does modify mailbox, but Ive logged a few toons checked mailboxes and used the AH and no errors at all.

if you don't use the blizzard mailbox at all, you can disable it in the options: but yeah, the blizzard skins really need some love. especially on TBC.
