do you understand the difference between what derrick has put here, and my
post? Derricks displays the data, mine sets it so that you can then just use
a simple select, so make sure you pick which will be useful for your
usecase. If you can use the update form to populate first and last names,
then get rid of the 'fullname' field and only populate the first and last
names from now on, that would probably also be smart. (we call this
normalising... getting rid of redundant data)
also note derricks use of TRIM to clean of the white space... thats also a
good idea i didnt use in my example
