One possibility would be to use a date picker.
How would a date picker prevent entering a date value into a
currency field?

It's a maxim among writers that if the intended audience didn't
understand what was written, it's the writer's fault, not the
readers'. The whole point of writing is to communicate effectively.
If one's writing is not understood, one has failed to communicate.
It might be a maxim, but it is not correct.
It *IS* the first thing to look at, but if a potential reader
decides not to read carefully, how would it be the writer's
fault? Yes, the writer might be verbose, etc., but it is also quite
possible for a perfectly fine piece of writing to be ignored.
The whole point of computerizing the collection of data is to save
time and improve accuracy. If a computerized system for collecting
data permits simple-to-prevent data entry errors, regardless of
whether better users could also prevent them, it has failed in its mission.
Oh, nonsense!
Any DE system will permit errors. If it is already known
exactly what has to be entered, there would be no need to have
DE. If not, then there are at least two alternatives. If the
operator enters the wrong alternative, how do you propose that this
would be caught by the program?
Here is an example:
An accounting system allows for the entry of G/L debit and
credits. Jo(e) Bookkeeper enters:
DR Bank Account $100.00
CR Cash Sales $100.00
Should the system allow this?
In this example, the amounts should have been $1000.00.
Has the DE software failed in its mission by allowing the above
entry? Please support your answer including a statement of how you
think the DE software should handle a case where someone made a cash
sale of $100.00 and wishes to enter that.
Sincerely,
Gene Wirchenko
