Hello @Anonymous,
So you added "shared parameters" to your sheet family?
And want to fill them in by clicking on the Question mark or by going to the project information to fill it in.
The only thing missing is a project parameter assigned to sheets or project information.
So try the following:
In your project template go to the manage tab, click on project parameters. Add the same "shared Parameter" as project parameter and assign this to the following Revit Categories (Project Information, and sheets).
As soon as the project parameter is added you can fill them in by clicking on the question mark or by going to the manage tab --> Project Information.
Hope this solves the problem.
If so, please mark this post as solution.
With kind regards,
