form_dropdown() always returns 0

[quote author="xwero" date="1212071956"]You are using an array for the dropdown name, the first argument only takes strings. I guess if you look at the source of your page you will see something like

Code:

<select name="Array">

I patterned my work with that of the CI User Guide's, which is:
form_dropdown('shirts', $options, 'large');

where,

I replaced:
'shirts' w/ a variable ($fby),
$options w/ another variable/array ($fby_values), and
'large' w/ yet another variable ($fby_default).

And looking at my source code, I didn't use <select name="Array">, instead:

function show_years() {
for ($x=date('Y')-150; $x<=date('Y'); $x++)
$years[] = $x;
return $years;
}
