Using a variable score as the result to determine pass/fail for lms

Hi am trying to work out how to pass the variable score to be the pass/fail for an LMS to read.

I am doing an ongoing assessment where the user gets a point deducted from 100% for everyone wrong click (only going to the next slide when they do eventually find the correct hotspot) but i am having issues trying to find a way to pass the final total from the assessment to a result slide.

i have followed guide regarding passing a variable, but this is only marking it as 100% as its asked 1 survey question out of 1 which obviously is 100%.

I want to be able to overwrite the Quiz1.scorepoints or whatever it is with the final total. 

please help
