ASP server side validation: Retaining form selections after posting

i am new to asp and would much appreciate your help with my problem.
i am trying to retain the selected "state" input from my form's drop down menu after it is posted and then gets returned to the form page for incorrect or additional input on the form. Presently, the input the user selected disappears when redirected back to the form. So when the user selects a state from the drop down list, how can i have it reappear in the selected field after posting so the user does not have to input it over again.
here is a bit of my code i have tried but it does not work as of yet.
looking forward to your reply

1. Before posting, store the value (in this case the selectedIndex of the SELECT) you want in a hidden control (INPUT TYPE = "Hidden" etc...)
2. Accept the value in the page accepting the post in a Server side variable.
3.When you return to the original page, obtain the server variable in a client side variable using javascript (var Clientvar = <%=ServerVar%> ; )
4. Set the selectedIndex of the SELECT as the client variable (<<Select_Name>>.selectedIndex = Clientvar)
