CMS Error

I added another content with the green plus at the topof the screen.
It was to add cms to the opening page of the web site.
My file structure is
The root is: home/eriss/public_html/

index.php which is the opening page that I created and is in the root. It links to the power store files in a sub folder called PStore4 where all the power store files are stored.

I added the new content page as indicate and copy the code from the index.php file thta I created in dreamweaver and placed the code fro the dreamweaver file into add content box I created cms. i. e. logo menu

I got the developer notes for each added content and placed it in the dreamweaver file. This is the first one

<?php echo WA_getCMSContent($database_PowerStoreConnection, $PowerStoreConnection, 'Opening Web Page', 'LOGO', false); ?>

I saved the my index.php file to the server root.

When I call the site to the broswer this is the error I got:

Fatal error: Call to undefined function wa_getcmscontent() in /home/eriss/public_html/index.php on line 47

line 47 is where i placed the Developer note

I supect it is a path problem but do not know where to look and do not want to change a path and have the rest of the store not work.

Please Advise.
Thanks
