I would like to have cell A11 set to show red via conditional formatting if
the cells F11:J11 and AI11:BF11 have either a number, date or text in them,
but excluding cells that contain X and the total is less than 12.
This is the formulae I have been trying;
=(COUNTIF(F11:J11,""&X)+COUNTIF(AI11:BF11,""&X ))12

Similarly A11 should go yellow if the total is between 12 and 25.

Any suggestions.
