multiple list bug?

Hello, I have a form which the follownig select <select name="interests" multiple size=2> A user can select any number of options, but when I read the variable $interests, it only displays the LAST item selected by the user. Is there a way to read the entire list? I would have thought that it might be an array but if that was the case it should print the word Array when I do an echo on $interests. Please respond to my email address since I cannot handle the volume of this list.
