Ebay users...question re max bid & reserve

Does anyone use ebay? Do you know what happens in this senario...

Something im bidding on, im winning the bid but the reserve is still not met. Theres still some time left on it but to try secure it i should put on a maximum bid ... since the reserve is not met would that mean my max bid wouldnt show anyway (if now one else bids) or would that bump my bid up if my max bid would meet the reserve?

Hope this makes sense?? Hope someone can help, thanks
