Hi there! I just finished the whole code but when I call playGame function this is what happens:
TypeError: Cannot read property ‘toLowerCase’ of undefined
at getUserChoice (/home/ccuser/workspace/javascript_101_Unit_3/Unit_3/rockPaperScissors.js:2:23)
at playGame (/home/ccuser/workspace/javascript_101_Unit_3/Unit_3/rockPaperScissors.js:57:20)

But when I call getUserChoice function, it works. Can you see the problem?
