Changing the usage of result (in my example the 3 snakeOrShack lines after the "snake or shack" if statement) will get rid of the "variable result is not defined" error. For anything else you would need to ask a question.

That just looks like none of the comparisons match. Note that the checkbox value wouldn’t be a list.

If the variable is created by the workflow, it won’t have a value in the document settings, since it is set by the workflow at run time. A variable manually created by right-clicking the variable pane (at the bottom of the workflow document) will persist between runs.
