Moving two Identical GameObjects Independently

I am creating a 2D Pong game using the tutorial found here: https://noobtuts.com/unity/2d-pong-game and everything has been going fine up until now. I created two identical Game Objects (rackets) and created a script for them to move up and down, however moving one also moves the other. I tried adding a second Axis and renaming it Vertical2 however the program doesn't seem to recognize the second axis. Can post script if needed.
