I complete all the steps, and my end result is working as expected (screenshot below), but it still doesn't pass me: "The 'Translate Survey Input' action is either missing, named incorrectly, or not positioned after the existing Get elements in the 'Translate Fitness Survey Input' flow. Review the 'Work with the Prompt Template in a Flow' scenario and related Help article for element configuration."
I've started from scratch a few times and used a new org, but no luck. Can anyone help? Am I missing something?

Hello @Caroline Fearey concerning the action, check your API name; it is written " Label the action Translate Survey Input with API name Translate_Survey_Input using any description you’d like". Yours has an extra "Fitness" in it.
