I am a new user and need help with an easy problem. I have a table that has two rows of data which has been collected over the past five years. One column is the date and the other is an output. I need to pull out only certain rows. The rows I need are the ones which are the earliest and latest date given in each month and each row in which the data point changes by at least 20 points. What would be a good way to go about this or where can I get the info on how to do this. <br><br>Thanks
