Error code help - XML Parse error

Ok, figured it out. so if anybody finds a strange HTML syntax error this might be it.

It was the use of “&” (ampersand) in the Inventory SKU name. Does not apply to the Inventory Title only the SKU name, once that SKU name was associated with a listing it would throw an error. That’s why I couldn’t find a syntax error while looking in editor mode, it was associated to the SKU name.
