Howdy La Mer

I have 3 columns with data in and a fourth I want to put either 1 or 0 in if the other 3 columns have all got the the correct data I am after.

I am looking for the following in the 3 columns

column 1 must be less than 2.5
column 2 must be between 22 and 35.3
column 3 must be greater than 0

If all agree I get a 1 in column 4 if not 0
