Your code is quite hard to follow as it's not clearly formatted. Not such an issue if it was a small fragment, but that not's the case here. Please go back and edit your initial post to add code tags (sorting out the spacing and indenting that got lost when you cut and pasted...).
Because of this line: if (totalscore = -1). You're assigning totalscore to -1 which will always succeed, and evaluate as true. Change it to if (totalscore == -1) to compare instead, which is what you want. Simple mistake.
Remember, one equals sign '=' is assignment, two equals signs '==' are comparison.
