Jumi extension php and css file's paths - Joomla! Forum - community, help and support

hello,

i installed jumi extension joomla.

i uploaded php files , 1 css file need make addition website.

i put pathnames them example:

components/com_jumi/order_confirm.php
components/com_jumi/review.php
components/com_jumi/includes/formvalidations.php
components/com_jumi/includes/config.php

now file order_confirm.php has code require formvalidation.php file:
require_once ("includes/formvalidations.php");

but when create new menu item points php file review.php outputs following warning , error:

warning: require_once(includes/formvalidations.php) [function.require-once]: failed open stream: no such file or directory in /home/content/37/9463737/html/components/com_jumi/views/application/view.html.php(40) : eval()'d code on line 3

fatal error: require_once() [function.require]: failed opening required 'includes/formvalidations.php' (include_path='.:/usr/local/php5_3/lib/php') in /home/content/37/9463737/html/components/com_jumi/views/application/view.html.php(40) : eval()'d code on line 3

does mean paths wrote each file in jumi not actual path these files?

any appreciated!

thank you,
al
