You didn't even return anything with the 'choosegear' function. Additionally, when 'math.random(1,#gear)' is being called; the number of items in gear is '0', which means you're trying to choose a randomValue in the max parameter that is lower than the min parameter. Since choosegear() refers to nothing [nothing is returned] that is why 'm' is being 'nil' at the moment.
still couldnt fix these errors.....
