Output is always zero

Jack816 (60)
The output for my "biggest" (Line 45) and "median"(Line 78) functions always returns zero. Could someone point me in the right direction?

Firstly, do you understand you have to input 100 numbers? Have you considered a smaller number, like 10 for example?

You don't appear to input 100 numbers, but you still attempt to find the largest value in the 100 values.
