I will explain what I am trying to achieve with an example
I have a column with a bunch of IDs, they can repeat. Then a have a second column with different values for those IDs.
On the 3rd column, I am trying to have a formula to sum all the Values from all the rows that have the same ID as the current row.
For Row 1 we have, ID = 1, so 5+6+2= 13
Any ideas on how to do that?
Go to Solution
Using the ColSum() function with a second argument to specify a By variable should work. The script below recreates your table, using a formula for the third column:
New Table( "Data",
Add Rows( 5 ),
New Column( "ID",
Set Values( [1, 1, 2, 3, 1] )
New Column( "Value",
Set Values( [5, 6, 9, 1, 2] )
New Column( "SumIf",
Formula( Col Sum( :Value, :ID ) )
Hope that helps,
