Need hands on help with quiz programming

We've got a particular way that we have to create our quizzes and I need some help from a smart Storyline programmer out there. 

We have courses that are split into modules. After the module, the learner has to take anywhere from 2 to 5 quizzes. Since these are really just knowledge checks, they aren't counting to the score or the LMS. Here's the tricky part, because we want to be approved by our education association, we had to make the quizzes act in a quirky way. They require that if the learner gets the question wrong, they are presented with two remedial questions that are similar to the original question. So, in effect, if there are 4 questions, each question has 2 remedial questions making a grand total of 12 questions that the learner could potentially answer. 

I've come up with a way to create the remedial functionality using variables, however, I keep getting strange behavior reported at different times. Sometimes, it's something small, but there are other times when I just can't figure out the problem, or it gets fixed because I moved the order of the variable triggers or whatnot.

Bottom line is, we're looking for a Storyline developer that has more experience and knowledge than i do to help us out. 

If any of the developers out there would like to take a look at the story file and/or contact me, I'd really appreciate it.
