Does anyone know a good formula for identifying the first value in a row that is less or equal to than another? For example, if I have the row: 35 34.2 33.9 33.8 33.9 33.6 33.8 33.9 34 35 36 37 I would like to identify the first number from the left that is less than or equal to 34 i.e. 33.9 in position 3. Thanks
