need that formula which i will put in F1 column
NOW HOW IT WILL WORK?
when i put any value in B1 Aswer show by F1 is 990
when i put any value in B2 aswer show by F1 is 980
CHECK
when i delete the value in B1 result come back to 990 instead of 980.

simply value B1 To F1 is 40 (B1=10 + C1=10 + D1=10 + E1=10) equal to 40
(B1=(cell Empty) + C1=10 + D1=10 + E1=10) equal
to 30
