I am able to read the values from the query string fine. However I am unable to set the value of the HTML textbox. When I try to debug the said statement it appears that the html textbox is null.

Aditya

Below is the javascript code I am using
<script language="javascript" type="text/javascript">
    window.setTimeout("pushSubmit()", 1);
    function pushSubmit() {
        var query = window.location.search.substring(1);
        var Whole_Name = getQueryVariable('Whole_Name');
        var cds_name = document.getElementById('cds_name');
        if (cds_name) {
            cds_name.value = Whole_Name;
        }
        document.getElementById('PrePopGateway').submit();
    }
    function getQueryVariable(variable) {
            var query = window.location.search.substring(1);
            var vars = query.split("&");
            for (var i=0;i<vars.length;i++)
            {
                 var pair = vars[i].split("=");
                    if (pair[0] == variable)
                    {
                        return pair[1];
                    }
            } 
  
    }
</script>

and this is the html textbox 
<input type="text" value="" id = "cds_email" name="cds_email">

When I add a breakpoint to the following line of code and step into it, it returns a null value
var cds_name = document.getElementById('cds_name');

Thanks,
Aditya

put textbox before script is getting executed..I think you are putting textbox after executing the textbox

<input type="text" value="" id = "cds_email" name="cds_email">


<script language="javascript" type="text/javascript">
    window.setTimeout("pushSubmit()", 1);
    function pushSubmit() {
        var query = window.location.search.substring(1);
        var Whole_Name = getQueryVariable('Whole_Name');
        var cds_name = document.getElementById('cds_name');
        if (cds_name) {
            cds_name.value = Whole_Name;
        }
        document.getElementById('PrePopGateway').submit();
    }
    function getQueryVariable(variable) {
            var query = window.location.search.substring(1);
            var vars = query.split("&");
            for (var i=0;i<vars.length;i++)
            {
                 var pair = vars[i].split("=");
                    if (pair[0] == variable)
                    {
                        return pair[1];
                    }
            } 
  
    }
</script>

I think you are putting textbox after executing the whole script

<input type="text" value="" id = "cds_email" name="cds_email">

// window.setTimeout("pushSubmit()", 1);
function pushSubmit() {
var cds_name = document.getElementById('cds_email');
alert(cds_name)

    window.setTimeout("pushSubmit()", 1);
    function pushSubmit() {
      //  var query = window.location.search.substring(1);
      //  var Whole_Name = getQueryVariable('Whole_Name');
        var cds_name = document.getElementById('cds_name');
		alert(cds_name)
      
       // document.getElementById('PrePopGateway').submit();
    }
    function getQueryVariable(variable) {
            var query = window.location.search.substring(1);
            var vars = query.split("&");
            for (var i=0;i<vars.length;i++)
            {
                 var pair = vars[i].split("=");
                    if (pair[0] == variable)
                    {
                        return pair[1];
                    }
            } 
  
    }
</script>

<input type="text" value="" id = "cds_name" name="cds_name">

I tried moving the textbox declaration before the javascript methods but it gave me an error.

    window.setTimeout("pushSubmit()", 1);
    function pushSubmit() {
        var query = window.location.search.substring(1);
        var Whole_Name = getQueryVariable('Whole_Name');
        var cds_email = document.getElementById('cds_email');
        if (cds_email) {
            cds_email.value = Whole_Name;
        }
        document.getElementById('PrePopGateway').submit();
    }
    function getQueryVariable(variable) {
            var query = window.location.search.substring(1);
            var vars = query.split("&");
            for (var i=0;i<vars.length;i++)
            {
                 var pair = vars[i].split("=");
                    if (pair[0] == variable)
                    {
                        return pair[1];
                    }
            } 
  
    }
</script>

<input type="text" value="" id = "cds_email" name="cds_email">
