Javascript and ASP

Hi,
I have a JavaScript Function that returns a numeric value.
How can I take that value and then use it with my ASP or VBScript Code.

I would use a hidden input box on a form. After submitting the form, ASP can read the value of the form variable and work with it as required

How would you set the hidden value

here is a quick page I put together:

Code:

<HTML>
<SCRIPT language=Javascript>

function SubmitIt()
{
    // set the value
    document.frmMain.txtJSResult.value = "HELLO WORLD!";

    // display that the value is set
    window.alert(document.frmMain.txtJSResult.value);

    //  submit the form
    document.frmMain.submit();
}

</SCRIPT>
<BODY>

<form name=frmMain method=post>
<input name=txtJSResult type=hidden>
</form>

<Input type=Button name=cmdSubmit value=SUBMIT onclick="SubmitIt();">

</BODY>
</HTML>
