From the
CGI pod:
popup_menu() creates a menu.
1. The required first argument is the menu's name
(-name).
2. The required second argument (-values) is an array
reference containing the list of menu items in the
menu. You can pass the method an anonymous array, as
shown in the example, or a reference to a named array,
such as "\@foo".
You need to pass a reference to a list to the
-values key of a
popup_menu:
popup_menu( -name => 'select', -values => \@files )
Please read the
CGI documentation carefully. It is well-written and has many examples.
