You're on the right path.

  • There is an underscore missing in "discount 10"
  • the second argument to partial should be the discount argument you wish to prefill in. In this case use amount=10

Use 10 instead of .1 since the function discount converts to percentage with "/100"

Post back if you need more help. Good luck!!
