I want to have a spreadsheet in which "Jason" only has access to populate information in Columns A-D, and "Rachel" only has access to populate Columns E-F on the same tab.
It's important for each person to be able to view the other's data that has been input, but is not allowed to edit/add to it.

Is this possible in Excel 2003? If not - is it possible in Excel 2007?

Thanks,
Alesia
