Adding % columns in Acc. Schedule

ClaudioPereira

I'm having a issue in Acc. Schedule. In one report, row 100 is a percent formula "Z2%Z1", in the same report i have the 3rd column (A3) adding the first 2 "A1+A2". If both A1 and A2 have values, A3 will show correctly, if only A1 has values, A3 will be blank. I don't understand why. Has any one else experienced this?

Thanks in advance for any insights
