==== Multiple choice If Then Else - Quick and dirty ====


Decision making is the hardest part im Wherigo programming. The good news is that once you have understood how it works, you are ready to build great cartridges.

Here is a quick multiple choice solution to the decision making problem:

=== Create a Variable (variable tab) to store the answers ===

{{ :create_your_first_cartridge:qadif_expression.jpg |}}

=== Create an Input (Input Tab) and ===

      - reference it to your variable
      - select multiple choice as input type
      - add your answers in the multiple choice field

{{ :create_your_first_cartridge:qadif_input.jpg |}}

=== Compare user input ===
 (stored in the variable answer) with the correct answer (Expression tab)

{{ :create_your_first_cartridge:qadif_expression.jpg |}}

=== Check the users answer ===
after each input (Input/Events tab)

{{ :create_your_first_cartridge:qadif_inputevent.jpg |}}


You should improve this basic concept by adding a Message that informs the user that his input was wrong and that he has to answer the question again. Also add a message that informs the user that he can see a new Zone after a correct input.
