hiding unhiding rows macro hierarchy

We're almost there! Just one small issue. Please see attached version 3. In order for the Tasks rows to hide/unhide I have to change the EmpList checkbox listing on the Tasks sheet. Other than that it's working fine! Am I correct that we need to add some event to toggle the SelectionChange box to "False"? Right now it always reads "True"....If it makes this run smoother I can always add a one-line Data Validation list ("REQUIRED") for the Required Tasks. I tried it and it works but it didn't make any difference with the current updating/refreshing issue.

This is very encouraging Nate. I've been plugging away on this for several months and you've been so helpful. Thank you. David
