Hi, I'm using the following calc to get the child average % displayed in the Parent row
=ROUND(AVGW(CHILDREN([% Complete]@row), CHILDREN(Duration@row)), 2)
This is working perfectly except for a #Div0 due to blank cells.
The duration is calculated from the difference between the Start Date and End Date
I know to use the IFERROR calc, but I'm struggling to work out how to wrap it in the above formula, any help would be appreciated.
