Error: circular dependency

I assume these are calc columns, is that correct?  I am aware of a circular dependency "issue" when you write multiple calc columns, and their incrementally refer to all columns in a table. It is very complex and I don't think I can explain it based on what I see. But my suggestion is that you don't write calc columns at all, but instead write measures. Read my article about the difference here. http://exceleratorbi.com.au/calculated-columns-vs-measures-dax/
