For the record, ERokc sent me an email and said he had proven to himself that the MATH was actually broken by using the Debug mode. But when he ran just that bit of code in a previously-cleared PLC, it worked. And then after that he could not duplicate it. So we're not exactly sure what occurred but the hypothesis is that when it was not working there was something in retentive memory that was causing this behavior. No way to know what that was at this point.
So, if you do get some kind of bizarre behavior like this, use the Debug mode in Do-more Designer to prove it to yourself. But please fully document it if you have time so we can try to duplicate (and thus, fix) the issue.
Another thing that would be useful is while it is behaving this way, create a DMLoader file: File --> Export --> Generate DMLoader image...
BobO can give the details of just exactly what would be useful to include in the DMLoader image and why.
