All of the html that appears in the php code should be moved below the php code... so this portion:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Authorised Access Delete User Just Vibe Family Only</title>
<meta name="Keywords" content="online radio, internet radio, online internet radio station, funky house, garage radio, urban radio, uk garage music, UK internet radio webcam, electro radio, funky house radio, webradio" />
<meta name="Description" content="Just Vibe Online Radio features Live djs playing 24/7.djs playing uk garage, drum n bass, electro house, funky house, urban, trance, old skool" />
Should be moved to just above the first <link> reference.
It also appears you have an extra "<head>" tag above the body that should be removed.
If you continue to have problems, please attach a zipped copy of the page rather than copy and pasting it so that we can correct and send back the updates.
