Cell D39 has the formula
=(D4+D11+D18+D25+D32)/5
I want the cell to remain blank until at least on variable is entered, but then I want it to calculate the average of only the cells that have a variable in them.
Just so I am clear
D4 = 20
D11 = 50
D 18 = BLANK
D25 = BLANK
D32 = BLANK
Average would be 35
Thanks
