COUNTIFS Between Date Range

Hi All,

So I have been working on quite an extensive formula and thanks to some help on here I was able to get the formula working as intended. However, I have now gotten an additional request to have the option to select a date range.

My existing formula is:
=COUNTIFS(data_source[Period],IF($S$1="-- Period --","<>",$S$1),data_source[Month],IF($S$2="-- Month --","<>",$S$2),data_source[Division],IF($C$3="-- Division --","*",$C$3),data_source[Cost Centre],IF($G$3="-- Cost Centre --","<>0",$G$3),data_source[Manager],IF($K$3="-- Manager --","*",$K$3),data_source[Job Description],IF($O$3="-- Job Description --","*",$O$3),data_source[Employment Type],IF($S$3="-- Employment Type --","*",$S$3),data_source[Gender],IF($C$4="-- Gender --","*",$C$4),data_source[Race],IF($G$4="-- Race --","*",$G$4),data_source[Age Group],IF($K$4="-- Age Group --","*",$K$4),data_source[Education Level],IF($O$4="-- Education Level --","*",$O$4),data_source[Service Years],IF($S$4="-- Service Years --","*",$S$4),data_source[Category 1 Q1.1],E$8)

on the data_source[Month] criteria section I need to do an additional check, I need to see if a date range has been selected. I will be creating a second date field in V2. So if the user selects a date in S2 only values match S2 need to be returned. If, however the user selects a date in both S2 and V2 all values within the date range needs to be returned. This is what I've come up with thus far for the [Month] criteria part of the formula:

data_source[Month],IF($V$2="-- Month --",IF($S$2="-- Month --","<>",$S$2),IF(AND(data_source[Month]>=$S$2,data_source[Month]<=$V$2),10,100))

I'm not sure what to put where the 10 is and the 100 is.

Here's the sample workbook
