I have not been following this too closely, but I don't understand the
algorithm used to get the above output.

Why not just have an else statement instead of the 'if'?

Not sure what you are trying to do, but each time through the loop above you
are reassigning @fieldValue (I would have named it @fieldValues since arrays
usually hold multiple values). Therefore, when you use @fieldValue below, it
only contains data from the last line of input.
