Template Fatal error

Hi I'm trying to install a new templates but I'm getting this error message. Can anyone help me please?

Fatal error: Call to undefined function templpageaddcomponent() in /home/pleasure/public_html/inc/design.inc.php on line 463

Your template must provide this function, look here:

templates\tmpl_uni\scripts\functions.php

function TemplPageAddComponent( $sKey ) {
 switch( $sKey ) {
 case 'something':
 return false; // return here additional components

 default:
 return false; // if you have not such component, return false!
 }
}

if you doubt - just reload fresh
templates\tmpl_uni\scripts\functions.php
from UNI template, usually template-builders don`t change this file
