One thing I'd suggest is to encapsulate that big and() statement into an expression rule, and in that expression rule just pass the entire CDT as a single rule input. That will make it easier to update in the future if you decide to add (or remove) required fields, and also will allow you to test easily. I'm not clear why your statement might be evaluating as FALSE when you're expecting a TRUE (i assume this is your issue, you don't exactly clarify), but the first thing to do would be to troubleshoot a bit more which is a lot easier in the Rule editor. (if it were me, the first thing I'd do is triple check against any typos, though.
