Development Tools Slack for the Techdegree Using Slack Effectively Basic Slack Formatting

i tried finishing this question but it comes back as incorrect , but i tried this in slack and it worked.

how can i make sure i get credit for this being correct?

This may be difficult to get a response because (1) you haven't provided a question or answer, and (2) it is part of a techdegree so it is blocked for those not enrolled.
