Rae, sorry to hear about Frodobut I'm glad to see that you were able to keep some of your frogs (if not all of them) with you. In bad times it's a comfort to have your pets with you.
Lynn is right, email Dr. Frye and see if he can maybe just give you some advise. I've never had any experience with a frog with a broken arm but I think keeping him in the cricket keeper with the bare minimum is a good idea. It's not high so there won't be much room for climbing but that's a good thing since you'll want to keep his movement to a minimum.
