Code Help Needed to Sort Data

This is great! Any idea why I get the error message that I get after I enter the dates? I hid some of the columns that I do not want people to see which may have caused this. The only columns that will be viewed that are not set up to view on this workbook are K & S. Some staff like to enter Type of Contact, "K" and some like to enter birthday, "S". But, the other columns I don't want them to see. I tried to look at the code you wrote to figure it out but I have no clue. Also, how did you get the worksheet lines in the second sheet to disappear? I am curious?
