[AccessD] Importing - 2 Little Gems

Hey All
Over the years when I have been importing Excel and Text files I have 
been using some routines I developed to check that the dates and number 
fields are correct.
Then voila about a month ago I found Access had 2 functions that are so 
simple to use.
Teach an old dog new tricks.
IsDate()
Is Number()
Works a wonder.
