Templates Question

Sometimes when I upload a new template to the template directory it doesn't show up when I access the site admin.  For instance, when I upload Template New to the directory, I access the site admin to change the template but the default template is the only one there.  Is it a permission thing??  or something in the new template file???

example

dolphin\templates\tmpl_uni\scripts

open BxTemplName

$sTemplName = 'UNI'; change for sTemplName = 'black';

dolphin/templates

tmpl_uni change for tmpl_black

open \templates\tmpl_uni\scripts

open - BxTemplConfig - change tmpl-uni by tmpl_black

// path to the images used in the template - change tmpl-uni by tmpl_black

$site['images'] = $site['url'] . "templates/tmpl_uni/images/";

$site['zodiac'] = "templates/tmpl_uni/images/zodiac/";

$site['icons'] = $site['url'] . "templates/tmpl_uni/images/icons/";

$site['css_dir'] = "templates/tmpl_uni/css/";
