Quiz question point values for incorrect responses

I have figured this out.   I created a variable called "Score".   With the questions in the question bank, I originally created them with the correct/incorrect feedback layers.  In this case, the correct layer only shows a flying green check mark and the incorrect layer shows a similar flying red X mark.  The layer only shows for 1/2 second and immediately takes you to the next question.   My quiz has a 1 min time limit.  The timed quiz function doesn't work right with a question bank, so I had to create my own timer which stops the quiz after the minute runs out.

Since I had these layers available, I put a trigger on each layer which adds or subtracts points depending on whether you got the question right.  Instead of the usual Results variable I am just displaying "Score". 

The nice thing about this is I didn't have to create FreeForm questions.  These are just the standard T/F questions.  SInce I was using the Correct/Incorrect layers, it was easy to add the variable adjustment on each layer.

It works perfectly now.

Thanks for your help.
