Ahh, I see. Fixed it. Though I have another question now - if I'm getting the inventory contents of a user using the trade link & manager.getUserInventoryContents, what should I pass in as the first parameter? If I pass in the link itself, I get thrown an error. If i pass in the ID besides partner=xxxxxxxx, I get an HTTP error 404. If I pass in getUserInventoryContents("[u:1:" + accountid + "]" ...), where account ID is the partner ID in the tradelink, I also get an HTTP error 404.
