Hello. We have a spreadsheet from one of our users, where he added 3 columns (N,O,P) onto the existing sheet, and while they look like the rest of the columns, there's something about them that will not allow N,O,P to be sorted along with the rest of the worksheet. A thru M can be sorted, and N-P - but not ALL together...the SORT function becomes greyed out if you try. I want to try and resolve this without attaching the file, if possible (sensitive info). if absolutely necessary, I can create an abbreviated version of it perhaps.
thank you in advance
