I am trying build a segment to get one time visitor who never returned back in the specific time period. Since we use evar for tracking visit number I am unable to use greater than option but I see greater than option in Distinct count. Instead of using greater than option under Distinct count can I use
Visit number is equal to 1
Visit number not equal to 1
Try changing your logic such that you exclude visits of 2 or greater than.
As you are already defining the user witch is equals to 1 in Include.
Now as they are they will cancel each other in effect.
You should use the out of the box Visit Number and create a segment like below:
This will exclude any Visitor from report which had visit other than 1st Visit.
