I can't use the Supplemental Spreadsheet. I believe it might be because its not designed to be very compliant with Mac software, though this is a guess. Its asking to unprotect it, then it asks for a password, and none of the relevant passwords are accepted. I've sent the problem through to "feedback" on the on-line screen and also through the GBCI through the "contact" links, but neither really feels like the right vehicle for making technical assistance requests. So this is 2 questions, really, first --is anyone else having this problem and is there a solution? and second--if I have a problem like this what is the correct avenue for assistance? thanks!
