How to count values between two dates (variables)

peter_bolin — Thu, 08 Mar 2018 00:43:03 GMT

I've seen a few questions regarding this, which have been very helpful, but I still can find the answer to this.

I created two variables, one which calculate three days before the first day of a month and the second which calculates three days before the end of a month. Here they are:

vEndDateminus3= date(monthend(APH_DATE)-3, 'M/D/YY')

vStartDateminus3= date(MonthStart(APH_DATE)-3, 'M/D/YY')

I have values called COI which I'd like to count how many occured between vStartDateminus3 and vEndDateminus3. This is what I have:

Count({<{'$(=vStartDateminus3)'} = {'>=$(=vEndDateminus3)'}>}[COI])

Not working! Any help would be appreciated!

try like this:

Count({$<APH_DATE = {'>=$(=vStartDateminus3) <=$(=vEndDateminus3)'}>}[COI])

I'd suggest you:

Count({$<APH_DATE = {">=$(=$(vStartDateminus3))<=$(=$(vEndDateminus3))"}>}[COI])

Double quotes are needed here.

Or may be -

Count({$<APH_DATE = {">=$(vStartDateminus3)<=$(vEndDateminus3)"}>}[COI])

If the variables are defined as dates, you will need

Count({<APH_DATE = {">='$(vStartDateminus3)' <='$(vEndDateminus3)'"}>} COI)

Thanks everyone, very helpful! I ran this to check if I could 1) use this logic as measure called #aphs 2) make sure there are COI's within the start date-3...end date-3 range and 3) audit my minus3 variable.

#aphs = Count({<APH_DATE = {">='$(vStartDateminus3)' <='$(vEndDateminus3)'"}>} COI)

I'm very new to Qlik so sorry for the delay response and perhaps my filters are the issue. Thanks agian.
