Use

   Use the menus described above to select the type of circuit and select the value to calculate by tapping the box to it's right.

(Hint: While it is probably a good practise to always make these your first steps when using this form, it can be done at any time - if you forget to select before entering values into the fields you won't have to clear the form and start all over. Electrist will recalculate using the existing values anytime you change the Display setting.)
