I try to model my own guitar by clicking "Build & Order Your Guitar"(Carvin), but all it says is
Fatal error: Call to a member function on a non-object in /homepages/22/d196472242/htdocs/cart/build.php on line 88
Anyone please help?
Just send an email to the website. It looks like a server side error, nothing we can do about it.
