Hello,
I feel like this is a simple problem but for some reason I keep getting "#INVALID OPERATION". I would like to have the formula look at the children rows and if any box is checked then check the parent row box, otherwise leave it unchecked. I came up with : =IF(CHILDREN() = 1, 1, 0). That gave me #UNPARSEABLE. So then I changed it to : =IF(CHILDREN() = 1, "true", "false"). That gave me #INVALID OPERATION.
Any Help?
