,Cant make changes to shader?

,Hi i’m very new to all of this, just started a few hours ago, I’m following tutorials basically but I’m stuck.

I’m trying to added a texture to the “shader” area but the entire thing is grayed out and I cant seem to make changes at all. In the video I’m watching the gentleman simple grabs and slides the texture into the Albedo square but I cant seem to do anything.

I’ve attached a picture showing the area in question in case i’ve entirely butchered the names and terminology.

Thanks for the help!

Try to create a new Material and apply it to the gameobject.
