Custom Gorilla Themes Admin Year Dropdown is gone

Im not asking for a solution, I just want some thought on what could have gone wrong.

I bought a Car Dealer theme form Gorila Themes.com and that theme has a feature to ‘Add a vehicle’ so when you click on it you can select your car’s model, year etc etc and submit. and Year is a drop down created from theme’s meta php file that looks like this.

“year” => array(
“name” => “year”,
“title” => $options[‘yeartext’],
“description” => “Enter vehicle year.”,
“type” => “dropdown”,
“class” => “dropdown”,
“rows” => “”,
“hide_in_search” => $options[‘yearhide’],
“width” => “”,
“options” => generate_years( $options[‘yearstart’], $options[‘yearend’] ),
),

What I did is, I added a extra field in the same page for “Body Type” and it worked fine. My code was,

“bodystyle” => array(
“name” => “bodystyle”,
“title” => “Body Style”,
“description” => “Enter body style.”,
“type” => “text”,
“class” => “dropdown”,
“rows” => “”,
“width” => “”,
“hide_in_search” => ‘Yes’,
“options” => “”
),
But now all of a sudden, the Year drop down field is gone. So I reverted back all my changes and tested again and again but the drop down doesn’t come back. I just want to know whether these drop downs are stored in the database or how could it be gone like that?? Thanks a lot.
