Not Sure if this does what I want

That is my PHP Code, but I am not sure if it is doing everything I need it to. It doesn't seem to be adding the winner_id and changing the status in the database to closed.

What I need it to do is
IF the counter has run down, then add the user_id of the latest bidder to the table auctions and row winner_id.

It also needs to:
IF the counter has run down, then insert 1 into table auctions, row closed

Is it doing that at all?
