How do I change my networks on Facebook?

I changed schools this past summer, and I need to change the network. But everytime I try to change it, it come up with this, ';You have changed schools within the last six months. Facebook does not allow frequent high school changing. You will not be able to change schools at this time.';



I'm fairly certain I've never changed it before. Is there a way I can get around this?How do I change my networks on Facebook?
