Set up looks right to me, but I can't figure out what I'm doing for program not to load correctly.

Writes binary right handed and hex left handed
I don't know which moderator moved this to the Java forum, but this is supposed to be in the JavaScript forum.
Anyway..
The biggest problem is that you do document.writeln(.... + result + ...) but you don't use result to calculate the result, instead you use sum/difference/product/quotient.
So this should be quotient instead of result.
A second thing, doesn't cause the program to fail but it isn't needed, You don't have to declare firstnumber,secondnumber, number1,number2 over and over again. One time is enough.
The shortest way i currently think of is this (without using functions)
