I am making a custom helper in mvc 3 and I m using the following line in .cs(class) page 

"<input type=\"submit\" value=\"{0}\" onClick=\"showOk()\";\" /><div class='messagepop pop' style='display: none'><form action='' method='post' id='new_message'><div><img src='../Images/x.png' alt='Exit'  class='msgPopImg'  onclick='closePop()' /><table bgcolor='#FFF0F0' rules='rows'>" + builder + "</table></div></form></div><script type='text/javascript'>function showOk() {var maskHeight = $(document).height();var maskWidth = $(window).width();$('#mask').css({ 'width': maskWidth, 'height': maskHeight }); $('.pop').show('fast', function () { });$('#mask').show();} function closePop() {$('.pop').hide(); $('#mask').hide();}", buttonText);

I m getting ‘Input string was not in a correct format’ error due to this part:-

<script type='text/javascript'>function
showOk() {var maskHeight = $(document).height();var maskWidth = $(window).width();$('#mask').css({ 'width': maskWidth, 'height': maskHeight }); $('.pop').show('fast', function () { });$('#mask').show();} function closePop() {$('.pop').hide(); $('#mask').hide();}
"

The modified code is:-

"<input type=\"submit\" value=\"{0}\" onClick=\"showOk()\";\" /><div class='messagepop pop' style='display: none'><form action='' method='post' id='new_message'><div><img src='../Images/x.png' alt='Exit'  class='msgPopImg'  onclick='closePop()' /><table bgcolor='#FFF0F0' rules='rows'>" + builder + "</table></div></form></div><script type='text/javascript'>function showOk() {var maskHeight = 1000px;var maskWidth =1000px;$('#mask').css({ 'width': maskWidth, 'height': maskHeight }); $('.pop').css('display', 'block');$('#mask').css('display', 'block');} function closePop() {$('.pop').css('display', 'none'); $('#mask').css('display', 'none');}", buttonText);

How can I solve this error plz let me know

    I don’t see a closing </script> tag in your code. You have that?

    Update:
    Try this:

    <input type="submit" value="{0}" onclick="showOk();" />
<div class='messagepop pop' style='display: none'>
    <form action='' method='post' id='new_message'>
    <div>
        <img src='../Images/x.png' alt='Exit' class='msgPopImg' onclick='closePop()' />
        <table bgcolor='#FFF0F0' rules='rows'>
            " + builder + "</table>
    </div>
    </form>
</div>
<script type='text/javascript'>
function showOk() {
    var maskHeight = '1000px';
    var maskWidth = '1000px';
    $('#mask').css({ 'width': maskWidth, 'height': maskHeight }); 
    $('.pop').css('display', 'block');
    $('#mask').css('display', 'block');
} 
function closePop() {
    $('.pop').css('display', 'none'); 
    $('#mask').css('display', 'none');
});
</script>
