Dear All,I have 2 problems.1. Please somebody can help me to do a cascade in Epidata?My database have 4 levels (Region, District, Health Aeria and Village). I want to make a cascade model. 
So, when i select one region, i want to only have the district linked to the r?gion. The same for district and health aeria and village.2. How to have results with addition of some fields (Integer). In this Epidata version, we can calculate hours and concatenate.
