Hi, Chris. I'm sorry for the trouble you're having. Could you
send us a URL or an HTML document where we can see this in action?
I haven't heard of this before (both 1Password failing on these
kinds of sites and also these kinds of form naming in general), but
it would not surprise me if special characters caused problems for
our form filling algorithm. With a proper test case, we can make
improvements to hopefully get this to work better for you.
Thanks for your patience and assistance while we work with you
