This may be far more simple than I think. What I'm trying to do is use the ArrayFormula to copy an existing formula to all the rows in a particular column.
To begin with, I have several columns along the lines of:
What I'm doing is adding the first three numbers and multiplying them by the fourth. I also have an IF condition in which, if the fourth column is blank, I leave the value in column 5 blank.
Now, I'm trying to convert this to an ArrayFormula to repeat this for all the rows in column 5.
So I went from:
=IF(ISBLANK(E2)=TRUE,,SUM((B2+C2+D2)*E2))
to this:
=ArrayFormula(IF(ISBLANK(E2:E)=TRUE,,SUM((B2+C2+D2)*E2)))
But what this does is, when I add a new row, ALL of the values in column 5 are set to the same value. Here is an example:
So, my first thought was to set the range on the SUM formula and change it to:
=ArrayFormula(IF(ISBLANK(E2:E)=TRUE,,SUM((B2:B+C2:C+D2:C)*E2:E)))
But that just makes all the values to sum of all of what the individual values should be...so, in my example, it works out to 435 (60 + 135 + 240).
What am I doing wrong here? The values in column 5 should be different in each row (e.g., row 2 should be 135 and row 3 should be 240).
Thanks!
