Answer 1

I believe this is actually what you want. The main thing was that the code should have been changing slider.src and not back.src. The code in the click event handler should be wrapped as a function (this was giving you the string to guid error). As for num++ % back.length, it's just a trick to replace the if statement.

Answer 2

You missed a closing bracket } for your if statement. Add one on line 14. Also, remove the semicolon on line 12.

Answer 3
