Dropdown menu/navigation disappear when select

Hello.

I’m not sure why when I select a branch on the Hours & Locations tab, the drop-down menu/navigation select disappears and would not navigate to the branch selected. I’m using IE9, but the weird thing is it works fine on FireFox and Opera. :confused:
I’m not sure if it is something in the script that’s messing it up in IE or what. Here’s the link to the preview page: http://library.cabq.gov/content.php?pid=445250&sid=3647425&preview=5534b11889d2d7a177415af5fdb14b5e Please let me know if I need to provide anything else. Thank you for your help.

Sorry, I just realized the above link didn’t work. Here’s the correct link.
