"Library" is not a standard Perl like module name, do you have a Library.pm, etc. that
is being loaded? aka something written in house by whomever... as an aside you
shouldn't use & unless you need them.

I am not sure what "label pop up" means, but it sure sounds client side to me, which
means you will have to use a client side scripting language (such as JavaScript). Perl
(with CGI) is 99.99% of the time server side. But if your flat file is stored server
side, then you will most likely need to either include the file in the html (with
javascript in it) or use a CGI to print the javascript converted flat file.

Actually now that I have written all of that, I think I get it... The values you are
passing to the sub need to be replaced with the actual values...aka you are passing
"flat-file-containing-options" needs to be replaced by a path with a file containing
the values (your flat file)... Then presumably the sub will translate that flat file
into the name/value pairs seen in the form. You will need to look at the docs for
Library.pm or whatever module contains the real implementation for PrintSelectBox.
Then pass it your values, rather than the description of what it is expecting to
receive.
Essentially your PrintSelectBox is just a wrapper around printing the HTML select box,
using a flat text file to specify the contents of said select box, including the name,
a default value, and who knows what arcane-null, etc. is. Though it doesn't seem to
have much sanity checking.
