I currently use the following formula below to caculate the number of days
worked by each emloyee

=SUMPRODUCT(('Employee Data'!$L$5:$L$260<"")/COUNTIF('Employee
Data'!$L$5:$L$260,'Employee Data'!$L$5:$L$260&""))

However this formulae was used when each employee information was seperated
in seperate sheets.

I need to add a string to this fomrula that calcualtes the number of
different days worked by each employee (all employee information is now
compiled in a single sheet

Hopefully this make s sense

Thanks
