I have a spreadsheet with 4 different worksheets. I basically want to sum the
information from the 4 worksheets on a separate worksheet. From worksheet1, I
want to count the cells that contain the letter "D" from B2:B30, but only
count those that have a "D" if "CO007" is in E2:30......same criteria from
worksheet2, 3 and 4. I started with
=count(if(worksheet1!B2:B30,"*d")+(worksheet1!E2:E 30,"CO007") +
count(if(worksehet2!B2:B30,"*d") etc. but that didn't work. Please help.
