For one thing, you are passing them as args, so in the function you cannot refer to them as $STRING and $Y - they are $1 and $2 respectively. For another, in the echo in the function you are escaping the $ on $STRING, so you are probably seeing "$STRING" anyway. And if you are passing the string and y values from the loop, you probably also want to pass the length from that context as well.

See the bash scripting guide among others for how this works.
