Footers in IIS 7- Fully Qualified Path

I have been trying to figure out how to find the fully qualified path on my website to read my associated footer file rather than a default footer.  

%windir%\system32\inetsrv\appcmd.exe set config "www.wilrob.com" -section:system.webServer/staticContent -enableDocFooter:true -isDocFooterFileName:true -defaultDocFooter:"My Footer String" -commitpath:apphost

This is the appcmd I used from an earlier post on footers.  I tried removing the "-defaultDocFooter" and it still wouldn't read the footer file when the website boots up. I get the "Error: Unable to read footer file". The home page is a static .htm page.

Any help would be greatly beneficial.
