How can I use logic to build a form?

I need to build in logic to make certain elements matter in my form.

Ie) If they pick two artsts then a series of questions relating to two artists populate; if 3 then 3, etc.

How do I do this?

You can build this logic by using our "Conditions" feature in the form builder's settings.
