TimeoutInterval = TimeoutInterval * 60 * 1000; //Converting to milisecond
TimeOutObj = setTimeout(function(){    

},TimeoutInterval);

try

  var TimeoutInterval = 1;
  TimeoutInterval = TimeoutInterval * 60 * 1000;

Do this :

var TimeoutInterval = 1;
TimeoutInterval = TimeoutInterval * 60 * 1000; //Converting to milisecond
var TimeOutObj = setTimeout(function(){},TimeoutInterval);
