How do I call one template from another?

[Saphrym]

Ok. I'm new to all of this, so I've got a question:

I'm working on the Header template and inside of it I have managed to create a column on the left where I want to put a seperate menu from the navbar. That's easy enough to do, but I want to create 3 child styles. I do not want to have to extensively edit each of the four styles everytime I make a change to a portion of the header that should be the same for all four, so I'd like to call SEPERATE templates in the Header one.

Is this possible?

I.E. Header includes MenuTop, MenuMiddle, and MenuBottom.

Being new and all, I thought I could call one template from another just by sticking a $ in front of the template title (I.E. $MenuTop). But that didn't work.

Is there a way to actually duplicate that?
