The following formula works to give a Yes or a No in C1 IF(AND(A1>=0;B1>=0);"Yes";"No")
How can that formula be increased so that not only A1 and B1 is used but that C1, D1 and E1 be included In other words, what formula can be used when A1>=0 and B1>=0, and C1>=0 and D1>=0 and E1>=0 so that Yes or No appears in F1
