3-column-page

I’m using the Branford Magazine Theme and it comes with a 3 column Page template.

I’ve used it once with good success. See HERE.

Now I want to make a second 3 column Page but I don’t know how. In order to make this page you have to place the Categoy ID #’s into the proper place in the template. So, it seems to me that I’ll need another template to place the new ID #’s into.

I’ve tried duplicating the template and giving it another name but it won’t show up in the editor.

Any suggestions?
