Why is my auction is archived?

[Tango]

I posted my first auction in the auction forum. It is supposed to end tonight so I went to check on it and give it a last day bump. But it was nowhere to be found. I did a search and found it's archived so I can't bump it so that people could see or bid on it. Does anyone know why this happened and how I can get it back out before it closes?

I just checked and it was archived because you HAVE to have the end date and time in the subject line. You can relist it.

Oh, I see. Thanks DBackFan. I didn't realize it had to be in the subject line as well.
