Forgive my ignorance here all as I am newer than I thought to solidworks. (used it 5 o 6 years ago)

I am trying to set it so that the variables in the model (description, dwg number, drawn by, etc) automatically populate when I create a drawing from that model. I have read through the variable mapping section in the admin guide but I must be doing something wrong or missing a step or something. Getting frustrated. can someone "dumb it down" for me?
