I don't have the manual or the calculator here with me to be sure of what I'm saying, but I think the calculator first gives you a choice of already created variables or, if your variable does not already exist, then you can type a new variable by entering the ALPHA menu.
So, once you are in MVAR "_ , go to ALPHA and type in your variable name.
I hope this works!
