Several things wrong. Line 41 calls an undefined function Test(), looks like it should be goldTest().
At lines 39 and 40 functions convOne() and convTwo() are called, but the returned value is simply thrown away.
It should look something like this:
double number = convTwo(input1);
or use one of the previously-defined variables, like this:
output1 = convTwo(input1);
Also, the variables output1 and output2 are not initialised or assigned any particular value, hence they may contain any random garbage value. At line 41 the two functions convTwo() and convOne() are then called using this garbage data, so the value returned will also be garbage.
