I would like to use this formula as a conditional formatting formula:
=IF(COUNTIFS(AccountsMonthsOrdered[Account],'Account Summary 2013'!$A$1,AccountsMonthsOrdered[Month],'Account Summary 2013'!F$12)>0,1,0)
It checks to see if the account name $A$1 and month F$12 appear together in the AccountsMonthsOrdered table, returning 1 if it does, and 0 if it does.
It works fine when it’s in a cell on its own, but no matter how I try to rephrase it Excel won’t accept it in the conditional formatting formula box.
The formula in conditional formatting does not accept Table columns… To remedy make a named range that points to the [Account] column from your table, reference the named range in your formula instead of to the table column. Same for [Month]
