Content Page and IE 8

 
Hey all,
I have a Master Page with css style sheet and Content page. i am using IE 8 and VS 2008. I have a content page with a textbox and a submit button, however the value of the textbox is not being captured when the user clicks the submit button in the code behind file(cs file). However it is working in Firefox and Chrome when I display the value in a message box, however not in IE .
Below is most of my Master Page
