#error in formula row of the form sum([1])/2
Greetings!
I have a necessity to use formula row in some forms to get an aggregated value of rows above, sometimes i have to use sum([1])/2 and this results me into a problem: in cells where formula is not valid (all values in specific column are blanks) it shows #error instead of values.
Question is, how to avoid that? like in excel for example =IF(A1="";"";A1/2)
Thanks in advance.
