BenMAP Pooled Valuations Results showing all Zeros

I am trying to run an estimate, and am getting some values for incidence, but none for valuation. Am I doing something wrong? Is there something wrong with my data?

All of my Delta Values were also inbetween 4 and 7, and in posts I see here, a lot of the delta values are in the double digits. Could this be part of the problem?

Have you tried using another valuation function to see if you get this same error? Also, are you using the EPA standard variable datasets, or did you modify your variable datasets?
