var biddates = new Array(0);
var lastpushbidid = 0;
var flag = 0;
function init() {
        getXML();
}

function pauseAuction() {
        var playimg = document.getElementById("auctionStart");
        var pauseimg = document.getElementById("auctionPause");

        playimg.src = "/images/play_up.gif";
        playimg.alt = "Click to Play";
        pauseimg.src = "/images/pause_down.gif";

}

Code (markup):

Especially the problem in below code.

    
if (lastpushbidid <  bidids[auction.length - 1] ) 
    {
        flag = 1;
     }
    else 
    {
        flag = 0;
    }
    
    if ( flag == 1 ) 
    {
          push();
          document.getElementById("msgzone").innerHTML = "calling if cond";
    }
    else
    {
        setTimeout("getXML()", 5000);
        document.getElementById("msgzone").innerHTML = "calling else cond";
    }
      
}

Code (markup):

If any new record inserted in table,it should call if (lastpushbidid < bidids[auction.length - 1] ) but why its calling else condition i cant understand so please guide me in this problem.I m try so much to solve this problem in last two days.....
