Project Parameter in Schematic Template

[robertferanec]

What do you mean by Parameters window? I do not really use templates, but I would expect this to work the way, that you can use parameter name in a template but you still may need to define the parameter and its value in your Project -> Project Options -> Parameters

I want to add a project parameter in schematic.
I followed the instructions given on altium official page.
.
But the project parameter doesn't appear in my parameters window.
I tried validating project, but the parameter isn't available to use (as stated on official page that it would be available to use globally throughout the project.)
Help!
