TypeError: Cannot set properties of null (setting 'onclick')

I have been following a freecodecamp youtube tutorial on full-stack development and I am getting an error and can not find the solution. here is the code:

it means you’re trying to set value to a property which doesn’t exist…

you can first try “troubleshooting” it, see if that property “onClick” event exist or not

otherwise consider sharing a “sandbox” environment link or “code snippet”, so that people can look into it and not just a picture (which is not always much helpful)

happy learning :slight_smile:

Why not just share the Replit link?

My best guess is you typoed the id used on the buttons in your selector. You have buton instead of button
