Similar to my problem with converting a big chunk of validation into
smaller chunks of functions I am trying to use Regular Expressions to
handle the validation of many, many time fields in a flexible working
time sheet. I have a set of FormCalc scripts to calculate the various
values for days, hours and the gain/loss of hours over a four week
period. For these scripts to work the time format must be in HH:MM.
Accessibility guidelines nix any use of message box pop ups so I wanted
to get around ...
