Re: how to indicate Not blank when I filter some fields?
Do you want Not Blank as in RRR*RR where the * is a wild card, or you want to filter on Not Blank for the entire string? If it's a dropdown selection such as in the graph area then you would have to use something like =A or =B or =C or =D or =E, but if it's in an input field where the users enters their own data normally you would think that you could use something like not = " " I am not at work right now to test it, but I don't believe this works.
Success is the ability to go from one failure to another with no loss of enthusiasm.
