Hmm - I was getting that error, too. I think maybe it’s the comparator we are using. I think if you use // your are saying “either/or” in which case only one part of the equation has to be true. Try using the &&(AND) comparator for your equations instead of the //(OR) and see what the interpreter spits out on the console.
this exercise isn’t very clear. I thought based on previous exercises that the hash symbol was for comments only I didn’t realize the contents were being accessed.
