Hi,
I’m going through the steps for the course “CDF Fundamentals”, and stuck on
Working with CDF: Integrate → Asset transformation → Switch to SQL editor (enter code).
Initially I was able to enter the code with no problem, and replaced all my data “Stacey1994”.. in all the applicable places. When the error occurred for the first time, I refreshed the page and tried to repeat the steps, but when I got to the “For NULL values on updates: Keep existing values (Default)”, the error message below keeps popping up.

Thanks,
Stacey
