A few ways you can approach this.

The javascript way :

   When the user selects from the second drop down, change the form's 
action attribute to wherever you want it to send, then append the values 
as a get request (action ="<?php echo $_SERVER['PHP_SELF']; 
?>?state=TX&city=Austin"). You can access the selected value of the 
dropdown using javascript and dom.


The PHP way :

   Create a session [ http://www.php.net/session ] and then load the 
variables into that session. If the both the variables have been loaded, 
then you can use header [ http://www.php.net/header ] to redirect to 
your next page.

( if you can post some code that you've been working with, that would be 
great )
