ive tried like 3 times to upload one of my videos and it aint working.am i doing something wrong or what?id appreciate yalls help.

There is a 10mb file size limit, you must upload an accepted format (wmv, avi and others) and a host of other things than can result in an upload error. What message, if any are you getting? Provide some more information and I'm sure someone can help you through the process.
