setInterval isnt working reliably for asp.net application

I have some code as follows:
My goal is to have a timer in java script that does some periodic checks and submits the form. I have used some alerts to see if my javascript is working. THe first time I tried the code below I got an alert window every second. But sadly, re reunning I dont see any alerts at all. If I lower the timeout i might get one alert.

I tried changing the alert to document.Form1.submit(); since that is what i ultimately want, but I dont see a form submission either. the html for the page:
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">

The working c# code: (at least I get my alert if its added to check()
if(!Page.IsPostBack)
{
SubmitButton.Attributes.Add("onclick","check();");
}

The not working very well javascript:
function check(){
setInterval("checkStatus()",1000)
}
function checkStatus(){
alert('checkfile');
}

use
setTimeout("doForwardStep()", 2000);

instead of
setInterval("doForwardStep()", 2000);

and to get repeatative timers call timer function from initialize function again like this,

function checkStatus(){
alert('checkfile');
check();
}

Modified as per below. I get a few form submissions , maybe 5, and then no more.
Do I need to be clearing and resetting something?
var t
var count=0;
function check(){
      setTimeout("checkStatus()",2000);
}
function checkStatus(){
      document.Form1.submit();
      check();
}

is your page reloading, then stick the setTimeout in the body of the document which will trigger itself everytime the page is reloaded, no need for functions.

well, the real goal is to periodically do a test, and only reload when the test indicates.
