It seems that nested IF’s don’t work. Is there a way to overcome this, or is it simply me doing it wrong?
also…
Is there a way to review all the keys in local storage? My memory is not that good 
How do you find an error if you do not see the values of variables on the screen?
Place the Label on the screen. Before each operation and after each operation, output to this Label the values of all the variables you are interested in. This will quickly detect the error.
I can assure you that the variable results are shown on the screen. I was in the process of making some screenshots to post when I figured out the problem (I think) in my head at least. I now have to trnslate that idea into blocks. Thank you for your help anyway.
