    Hi i'm developing a javascript program that requires the user to input a number and then displays all times tables from that number. I've got all that working but i need it so that it continuously keeps displaying times tables until the user types -1.

    
<html>
  <head>
    <title>Times Tables</title>
      <style type="text/css">
        body {
              background-color:#000000;
              color:#FFFFFF;
              font-size:30;
              text-align:center;
             }
      </style>
  </head>
  <body>
    <script type="text/javascript">
    var limit, count, equals;
    count = 0;
    document.write("<h1>Times Tables</h1>");
    limit = prompt("Enter a number", "");
    if (limit == null)
   {
    document.write("You clicked cancel. There will be no numbers displayed");
   }
   else if (limit == "")
   {
    document.write("Please enter a number");
   }
   else if (limit != parseInt(limit))
   {
    document.write("Must be a valid number");
   }
   else
   {
     while (count <= 12)
     {
     equals = parseInt(limit) * parseInt(count);
     document.write (limit + " * " + count + " = " + equals);
     count = parseInt(count) + 1;
     document.write("<br /><br />");
     }
     }

   document.write("<br /><br />");
   document.write("<input type='button' value='Do Another One' onclick='window.location.reload()'");
   </script>

  </body>
 </html>
    Code (markup):
    Anyone tell me how i would go about doing this? Many thanks for any help given.

    You want that after displaying the table, the script ask to enter a number again and again until the user will type -1?
