Hi, I am checking a challenge step and am being told (incorrectly, I think) that my org is not configured properly. it keeps saying:

Challenge Not yet complete... here's what's wrong: 
Variable 'AccountRevenue' isn't properly configured. Check the instructions

I have checked an rechecked.... how do get  past this?.
