accessing a code behind variable from aspx

hi experts, the below is trivial but it is driving me nuts!
for simplicity i am addressing my problem like this, i am doing the following code in the code behind:

public string x = "L";
            private void Page_Load(object sender, System.EventArgs e)
                  if (!IsPostBack)
                        x = "ss";
                        x = "ddd";

and am trying to access variable x from the aspx like this:
<td><%# x %></td>
my actual goal is to have more complex coding but have reduced my approach to first accessing x in its simples form.  just that i haev tried this on 2 different webforms now and am getting an empty string.  on other webforms i have used far more complex similar functionality and either i am missing some webform setting or else some magic is determining that this does not work, the end result is that i am going crazy. your help would be apprecaited. 10x a lot.

it works great 10x, I have worked wonders with # but always giving hassles until it works, once it works all is fine. do you know fo any issues? is = the correct syntax to say 'evaluate'? i will use the = to concatenate strings inside a javascript open window and so forth.

solved: it just happens (correct me if i am wrong) that you cannot put a runat=server if you want an evaluation within the tag, so i removed runat=server and it worked fine. 10x for the good tip pratima mcs
