    Ajax Poll

    Hello, I would like to know how to publish the Ajax poll http://www.w3schools...p_ajax_poll.asp in my website that works the same way it does in the demo page. The demo page shows the results in the same page without disturbing all the content around it. When I install this php in may page, it echoes the results in a blank page intead of appearing in the page and blending it with the rest of the content. HTML= <html><head><script type="text/javascript">function getVote(int){if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("poll").innerHTML=xmlhttp.responseText; } }xmlhttp.open("GET","poll_vote.php?vote="+int,true);xmlhttp.send();}</script></head><body><div id="poll"><h3>Do you like PHP and AJAX so far?</h3><form>Yes:<input type="radio" name="vote" value="0" onclick="getVote(this.value)" /><br />No:<input type="radio" name="vote" value="1" onclick="getVote(this.value)" /></form></div></body></html> ----------------------------------------------------------------------------------------------------------------------PHP= <?php$vote = $_REQUEST['vote'];//get content of textfile$filename = "poll_result.txt";$content = file($filename);//put content in array$array = explode("||", $content[0]);$yes = $array[0];$no = $array[1];if ($vote == 0) { $yes = $yes + 1; }if ($vote == 1) { $no = $no + 1; }//insert votes to txt file$insertvote = $yes."||".$no;$fp = fopen($filename,"w");fputs($fp,$insertvote);fclose($fp);?><h2>Result:</h2><table><tr><td>Yes:</td><td><img src="poll.gif"width='<?php echo(100*round($yes/($no+$yes),2)); ?>'height='20'><?php echo(100*round($yes/($no+$yes),2)); ?>%</td></tr><tr><td>No:</td><td><img src="poll.gif"width='<?php echo(100*round($no/($no+$yes),2)); ?>'height='20'><?php echo(100*round($no/($no+$yes),2)); ?>%</td></tr></table> Thanks.
