The attched is a dummy sheet based upon a poorly developed worksheet containing hundreds of lines. What the end user wnats is to be able to filter based upon the User ID in order to show the information which has been inputted by various users. For example by filtering based on user 1645004 rows 1 to 8 would show; filtering based upon164005 would show rows 19-36.
This is more than just using the filtering option in Excel. Is what the user wants possible? VBA code is fine.
Using Access is not possible.
