Trailhead Lesson reference: https://trailhead.salesforce.com/projects/quickstart-lightning-experience-sales/steps/qs-lex-sales-4
The lesson is a carryover from a prior lesson: https://trailhead.salesforce.com/projects/quickstart-lightning-experience-sales/steps/qs-lex-sales-3

therefore the source of the record created came from the qs-lex-sales-3. I found that when I tried to submit for challenge I get the following error:
Challenge Not yet complete... here's what's wrong: 
The record was not created correctly.

This does not make sense when the prior record was created by prior lesson and now has a problem to complete the existing? The instructions show the following update to the record name: 10,000 Units (Opportunity)

1. Amount from 100,000 to 120,000
2  Close date. (to present date).
3. Stage from 10 prospecting to 100% -Closed/Won.

Appreciate feedback.
Thanks, Fred Flores 

Trying to complete the "HUNT YOUR PROSPECT" unit, getting the following error message when i try to complete the creation of the Opportunity:

"Challenge Not yet complete... here's what's wrong: The record was not created correctly"
Unless there are invisible steps in this Trailhead, I have completed them all.
Is it possible this trailhead has an error?
