Typo in hint 3 for spinal tap case

On this page:

The hint 3 says:

The tricky part is getting the regular expression part to work, once you do that then just turn the uppercase to lowercase and replace spaces with underscores using replace() .

but it should actually say “replace spaces with dashes” not underscores

Hey there,

Thanks for bringing this to our attention. I’ve updated the hint in the guide post.
