  1. What is the expected behaviour (what are you trying to achieve).
  2. What is the actual behaviour?

Without background information it's difficult to work out exactly what assistance to provide.

You should always add some information about your problem when asking for help.

The task you are on is asking you to replace plain javascript with jquery. To select a class in jquery you use "$('.classname')" instead of "document.querySelector('.classname')". For hiding an element you use "hide()" instead of "style.display = none".
