The logic map and tester

At the top of the Logic tab, How it flows shows your pages in order, what each rule does to which question, where people can skip to, go back to, and where they can end.

#Checks

Underneath, Formkit lists anything that looks wrong: a rule reading a deleted question, a condition with no value, a jump onto the same page, a jump back that nobody could get out of, a rule that reads an answer given after the question it affects, options all hidden, or an ending no rule leads to.

#Try it

Switch to Try it and pick answers. It runs the same rules the live form runs and shows the pages people see, the ones they skip or see more than once, what is hidden or required, and which ending they reach.
