Ok so...

The 14th, 15th and 17th I would like counting the number of "P"'s there are, divided by the number of cells containing "something". I have this set up nicely for previous weeks, however I've become stuck now that the days I want are non-consecutive.

Previous weeks I use the formula: =IF(COUNTA(BN3:BR3),(COUNTIF(BN3:BR3,"P")+COUNTIF(BN3:BR3,"L"))/COUNTA(BN3:BR3)*100,"")

Now I'm looking at something along the lines of: =IF(COUNTA(BT3:BU3,BW3),(COUNTIF(BT3:BU3,BW3,"P")+COUNTIF(BT3:BU3,BW3,"L"))/COUNTA(BT3:BU3,BW3)*100,"")

It would appear they don't like the comma before the "P" and "L"

The cell under Week 13 % is where the formula should be going.

HS | HS | ||||

14/06 | 15/06 | 16/06 | 17/06 | 18/06 | Week 13 % |

P | P | UA | P | UA | #N/A |

Thanks in advance folks
