I am trying to count the number of times specific data occurs across
multiple
worksheets in the same workbook. I thought COUNTIF would work, but I don't
seem to be able to set the range properly. basically, I want to always
look
in the same cell on each worksheet and count the contents in a summary
worksheet. Any ideas??
