Thanks for the response, SGIII. It just seems like every time I want to convert from Excel to Numbers, I run int fundamental problems. Another example revolves around printing. First, you cannot select the print area. At least I have not been able to figure out how to do it. For many of the spreadsheets I use, I keep a running tally of data. Example, every week, I enter sales by client into a spreadsheet and want to print just one weeks worth of data. In Excel, I highlight the cells I want to print, the header and left columns that contain the static data are already frozen and I am able to select to print the selection only. I have not found a way to do this in Numbers. Last, when I copy a block of cells from Excel into Mail, the numbers align properly on the right side. In Numbers, while the cell formatting is generally maintained better than Excel (borders, text formatting, etc), the numbers are left justified. WTH!! Makes no sense to me.
Also, Excel has been widely condemned as being blotted. But, when I look at Activity monitor, Numbers and Pages take up more memory than Excel and Word. So, fewer features and more memory.
Maybe someday Numbers will be the champ. But, not at this moment in time for me. All of these small, nagging issues cause me to pack up my bags with Numbers and move back in with Excel. I don't want to...I have to :-)
