Thanks Cory. For the 2018 YOY change, it looks like you hardcoded 500% there, when it should actually be a % change calculation ie. (Revenue 1Q18/Revenue 1Q17) -1. Additionally, I can't tell how you are calculating maintenance revenue, but it looks like you might not be taking into account churn, or the price increase. 

Please see this worksheet and match your answers to it. 

Thanks again,
Chris
