hello all. i've recently built a function that is used to
manipulate a string (basically it pulls the last name out
of a full name....minus any prefixes and suffixes, etc).

the function works fine, and i'm pleased with it.
however, when i try to use the function in a new excel
spreadsheet it isn't recognized. when i place "getlastname
(a1)" in a cell, all i get is #NAME?.

any ideas as to how i might be able to access the function?

thanks in advance!
