I keep getting the error "On the 'Child Campaign' custom button, we can’t find the expected value for the 'campStartDate' parameter. Be sure to make the 'campStartDate' variable equal to {!TEXT(Campaign.StartDate)}."
Perfectly fine! Except that I am fairly sure I have the formatting in correctly:
Not sure how to get Trailhead to notice, though...or else, what am I missing?
