You mention concatenating your variable into a print statement can you explain what you exactly mean by that because I'm running into the same problem?

Ayy Fahim, It looks like those are all error messages you are receiving in the console upon trying to run your code. Could you possibly post the code that you are working with in the work space so I might look at it and try to point you in the right direction?

Hi Micah, I've figured out actually since you mentioned it may have to do with my code. I wasn't concatenating my variable to my print statement properly. thanks for the help!
