In support calls and mails we so often have the problem of people asking, why they don´t see numbers and only get a question mark.
OK, we can
format the number in a field
round the outcome of a formula
stretch the field to absurd length, most commonly the longest length one would normally think of (what tends to be the problem)
but often numbers don´t represent calculatable stuff. Take for example the number of water or electricity meter. If you think, you have formatted the field to handle all possible numbers, support has a new number and even longer number for you.
Life would be much easier, if FileMaker instead of showing this damn question mark would show a part of the number and add "..." if it doesn´t fit or would automatically decrease the font size or do both ?
Question mark should only be shown, if a calculation isn´t possible or is a division by zero - but for this an error code would be more helpful than just this question mark too.
