Variables in library objects

Hi,

I'm working on a template for my company and I'm trying to build some library items that can be inserted when someone creates a new page from one of the preset layouts.

The library item that I've created contains a variable "language". When I place the library object in a course where the variable already exists, it creates a new variable "language_1". It does this for every new object inserted, so none of them work together unless I go into all of the parts of the object and reset the target variable.

Is there a way to either build a library object or insert it in such a way that doesn't create a new variable when it is added?

Thanks

Dennis
