Where can Building Blocks be stored?

1. Do you know where your building block is stored?
2. Is it in the Building Blocks.dotx file? Is it in the document template? Is it in another template that is already loaded as an Add-In? Is it in a template that you have to load before you can use the building block?
3. What kind of building block is it?
4. Why are you using a macro for this?
5. What is it supposed to do when it is inserted?

Right now, you are asking for help to get home. I don't know where you live or what kind of transportation you might have. Need some more information here.
