I would like my parent status to be RED when ALL children balls are red, yellow when at least one is yellow, otherwise green. I found this formula below in a thread, but I can't seem to get Parent to RED when ALL are red. Can someone tell me what is missing? Thanks!
=IF(COUNTIF(CHILDREN(), "Red") > 0, "Yellow", IF(COUNTIF(CHILDREN(), "Yellow") > 0, "Yellow", "Green"))
