Summary sheet is first sheet.

Insert a new sheet to right of summary sheet......name it Start

Insert a new sheet at end of sheets.........name it End

In your summary sheet enter in a cell =COUNTIF(Start:End!D254,"C")

When adding more sheet make sure they are inserted between Start and End
sheets.

Column D Row 254 contains the text "C" in all worksheets (which have
different numeric names..i.e. 1400 thru 1423)

In a summary sheet in the same workbook I need to count the number of
instances "C" occurs.

I will later use this formula to count it the value is "D" or "E"

Thanks
