You don't have an "else" case if the x value is out of bounds; it only
handles the y value error condition.
Also, it would be a lot more simple if you were dealing with ints instead
of strings:
func fix(x, y int) {
if 1 > x || x > 15 {
handleError()
}
if 1 > y || y > 15 {
handleError()
}
proceed()
}
You could always scan them to ints and test them as ints, and then convert
to string if your app logic needs it.
