Sum multiple worksheets and summary tab that would sum and count by rep name
 

I have multiple worksheets within the workbook. There are tab 1,2, 3, etc. Each tab represent days of month(May).

I have a rep stats summary tab to sum up by rep. I would like to know if there is a easier way to create this formula? A rep may be listed more than one time in a day or per tab.


Attached is a copy of the excel. I am trying to see if there is a faster to sum up all worksheets and count rep in the summary tab.

I am using excel 2010.

Someone told me to create a name list and use the formula below. I think I am doing my name list incorrectly. I keep getting #REF!


=SUMPRODUCT(COUNTIF(INDIRECT("'"&SheetList&"'!c:c" );B3))
