So the "print(html)
" at the end of the program wipes out any message that the rest of the program would have displayed.

2,890 PointsOk so It works, I had to create another javascript file. I was wondering if i could do it all on one file instead of multiples?
Steven Parker
231,236 PointsSure, when I was testing I had only one file.

231,236 PointsI'm not sure what you mean by "did that". If I just remove the last line the program works as expected.
Be aware that you won't see anything until after you type "quit" (see the Teacher's Notes for details).
