PowerCMS and PowerStore Integration Challange

I am currently running both PowerCMS and Power Store on a client website. Both are working fine but I would like to use PowerCMS to allow the client to modify text section of the PowerStore Index (Home) page. I read in the forums where they can be integrated. My current configuration is as follow. PowerCMS is in the root directory of the site. PowerStore is in a sub-directory called "store" in the root directory with all of the PowerStore files and folders in it. I have tried adding the 2 lines of PowerCMS PHP code to the top of the store home page and then the PowerCMS content string to the area of the page I want the text/images to show up in (same as I have down with each of the main web site pages and as I read here in the forums) the problem I am having is a code error occurs when the page loads. I have checked the code and everything seems correct. My guess is that I have to do something else because the store files are in a root subdirectory "store" and PowerCMS is in the root. Can you help. I can provide access to the site if necessary for you to review.

Thanks,
Mike
