3. Show Current State 1. Input current state data  Simply enter in values in the green boxes  The fields in yellow will be calculated by the model

4. Missing Data? 1A: What if I you don’t have all the data?  You probably don’t, so the model will calculate the data you do have and, if you know the figure is wrong, you can correct it by entering an “override” value
