Select Menus

I am trying to figure out how to pass one selectedIndex value to another select menu on a subsequent page without opening the page in a new window. I know how to pass information from one text field to another using Request.form or a Session, but I am not certain how this works with select menus. I have seen other examples that require you to open a new window, but again I would prefer not to do this.

I have two different select menus. This appears on the first asp page.

<form class="fbox-form" name="form" action="" method="post"

<select name="movietype" onchange="this.form.action=this.options[this.selectedIndex].value">
<option value='' "> </option>
<option value="dvd.asp">DVD</option>
<option value="tape.asp">Tape</option>
<option value="reviews">Revews</option>
</select>

<select name="area">
<option value=" ''> </option>
<option value="North">North</option>
<option value="Southwest">Southwest</option>
<option value="East">East</option>
</select>

<input name="continue" type="button">

</form>

The next page has the exact same select menus as above and I would like it to populate the same value the user chooses from the first form page. I should state that the first select menu does redirect the user to different pages, however it should not matter because the above options for the select menus are consistent on all the pages the user is redirected to. I'm assuming the answer to my query will consist of utilizing ASP and JavaScript, however if not, I'm still game.
