Having new operator comparisons such as :
- IF value is NOT between X and Z Values...
than text color "red"
- If Value of Field B is Higher than Field A...
Than text color "red"
Yes, thats exactly what I ve used for both case.
1) I though that case 1 could be joined in just one single line...whenever the operators <> would/could be agregated.
2) as for the 2nd case, I think that it implies an extra formula field appearing (also) on the form which is not always practical.
That is also the Matter of another Topic I wrotte about how to possibly start to benefit/use hidden (existing) fields in the form formulas ...without having to display some "live".... :)
For your second request the only way I can think of accomplishing this as of now is by adding a Basic Formula that subtracts Field A - Field B and then adding a display rule that checks to see if the formula is less than 0.
Field A = 20
Field B = 30
Basic Formula (A-B) = -10
IF Basic Formula is less than 0 then B is greater than A
For your first request you can do that by setting the rules displayed below.
