I have never been able to get the Hide Detail/ Show Detail Commands to work for me in Excel:Mac 2001. I have opened the View:Toolbars:Customize window, scrolled to the two commands, and dragged them to the toolbar. They look as though they are active, i.e. The icons are fully drawn, but when I select a column to hide in a spreadsheet the icon greys out and the command cannot be invoked. Ironically, in a spreadsheet created with a previous version of Excel, (converted to Excel 2001 format) and containing the Hide/Show Detail "plus" and "Minus" tools, the buttons within the spreadsheet function properly, although I cannot seem to expand the rows and columns over which they operate to incorporate new data. Any suggestions, please? Sam Bays Tel: (617) 232-3705 Fax: (617) 232-8351 Cell: (802) 236-0690
