I have the following formula:

=SUMIFS('Future Sales'!$N$2:$N$5000,'Future Sales'!$X$2:$X$5000,"Flight Only",'Future Sales'!$F$2:$F$5000,"

**Apr-2019**")

However i would like the date to change when i drag it down... when i drag down, i always get Apr-2019, however i would like May-2019, Jun-2019 etc...

Or is there another formula i use.

I have one tab with data on it (as per the above) and i am looking to find out how much of that data has Apr-2019 etc... on it.

Thanks in advance!
