Field Name: "Month - Prior Months Total Target" Formula: If([Month - Prior]=true,[Target Total])
Filed Name: "Month - Current MTD Total Target" Formula: If([Month - Current]=true,[Target Total]*[Month - percent passed])

Filed Name: "Month - percent passed" Formula: If([Month - Current]=true,[Month - Day num]/[Month - days in each])
