i tried code in local host , got desired output in google chrome. when tried same page in firefox , other browser, failed work. checkbox validation working fine. in advance

from personal experience, have noticed chrome more forgiving when comes little errors. unusual how not getting error in debug box @ all... but, place can see reading code define variables a,b,c... recommend placing comma after each. so, get:

var = parseint(answer1), b = parseint(answer2), c = parseint(answer3), d = parseint(answer4), e = parseint(answer5), f = parseint(answer6), g = parseint(answer7), h = parseint(answer8), ii = parseint(answer9), j = parseint(answer10);

then here think have error. have var c = ... 1 time again after defining c. so, seek removing var right there.
