What's the problem? 1) call alert? 2) get value of text box, 3) parse to integer; 4) compare integers; 5) write if statement based on condition? :-)

6) Find Javascript functions using Google? MSDN?

Dear Shashwath,

Look this sample code:

XML

<SCRIPT LANGUAGE="JavaScript">
  function testResults (form) {
  var TestVar = document.getelementbyid('txt1');
   if (TestVar>15)
   {
    alert("You entered more then 15 days")
   }

  }

Thanks
