I've built the variable Account Revenue according to the instructions but when I verify the step I get this error "Variable 'AccountRevenue' isn't properly configured. Check the instructions."  Here's a screen shot of what my variable looks like.  Please can you help me find my mistake?  Thanks!

I finalized with Success the "Build a Discout Calculator" since it work perfectly on my Playground #02 environment.
However, I get this nasty message which prevent me to validate this challenge. What should I do ?
