Hi, I'm working on the Create Forecasting Reports trail. I'm getting an error when I check the challenge. "Challenge Not yet complete... here's what's wrong:  Couldn’t find report type label 'Forecasting Details'. Please double-check the instructions." This is what I've done in my org. Thanks!

Hello,
I tried many times... but receive the same error message : "Challenge Not yet complete... here's what's wrong: 
Formula in custom field 'Account Annual Revenue' is not correct. Check the instructions."
I followed all instructions & get the right results. It's a basic & very simple formula.
Do someone else encounter the same issue ? Any solution ?
