I seem to get the "expected" result when I set the Height and Width to "unequal to" vs. the intuitive setting of "equal to" in the Callas check.
I have recreated the problem and have written a BUG against it. Feel free to contact Xerox support for the raising of a problem report.
Can you provide me with an example (e.g., ffc file/screensnap) of what you are trying to accomplish? I am having trouble following the formula you are trying.
OK, so I have another problem, what is tolerance in "Check Width and Height"?
When I choose "is equal to" and for example give 40mm in trimbox width and 41mm in variable - the result is not an preflight error. It is wrong becouse 40mm isnt equal to 41mm. When i give 42mm in variable there is a preflight error (so it is working OK).
I have tryied to do "fit between" but when I was trying to substarct 0.1 mm in first variable and add 0.1 mm in secound (after "And") it couses an error.
