58098 create a dropdown for checkout

Hi: Please see our checkout process. [login to view URL] Enter a number of bands, then go to the second page. See the donation part? Underneath that, we want people to be able to earmark their donation for a specific college. But there are a lot of colleges in the united states. So, a simple dropdown menu will not do. Too many schools. It needs to be a double dropdown, or something - where you first select a state, and that generates a list of just the schools in each state. here are the schools in each state (click on a state to see the list). Some states have just a few schools, but some have many...so that's why I think 2 drop downs would be best...but you tell me. I am open to creative solutions. [login to view URL] Thanks! (to be clear, ALL we are asking you to do is create the drop down or whatever you think works best, and hook it up to our order system).
