Re: I guess this is a newbie type question.

Thanks, that did it.


Now for the next question.  In the main part of the program I declare this.

my %spinner;

Then later on in a subroutine I do this.

$spinner{$hour_type}{$year}{$day} = new Gtk::SpinButton($adj, 0, 2);

As well as the various other attributes you can adjust on a spin button.


The problem is that later on in another sub-routine when I try to read my
spinbutton with this.

$spinner{$hour_type}{$year}{$print_day}->get_value_as_float();

It tells me that it can't call get_value_as_float with an undefined value
(or something close to that).

Any ideas on what I am screwing up now?
