I was scratching my head for a while on why I was getting this error when i was clearly seeing my button with it’s respective id of “substract”.
Turns out there’s a typo on the actual checking script, as you can see it’s looking for an element with the id of “subtract”, without the “s”.
Hopefully this gets fixed soon, thanks for all the awesome material! Link to the challenge:
OH, now I feel dumb. It’s really similar to the spanish word with the same meaning so I was clearly confusing things here.
I apologize! I’ll flag this topic
