Question:

I created a Visualforce page for adding a custom button to objects, but I can't select the page when adding a custom button to an object.

Answer: 

For each object where you want to use the Action Launcher, you need to create a separate Visualforce page. In the code line standardController="OBJECT" you replace OBJECT with the API name of the object.

See Add the Action Launcher to other objects‍ for more information.
