Protecting summary page

[Sharoo]

Hi, my problem is that I have a 26 page payroll document that completes a single summary page in the same workbook. I used to be able to select all pages delete the former entries for each staff member all at once while not effecting the summary page, now it is also deleting information from the summary page. Each page links to the summary page, deleting inputted information from each of the 26 pages is very time consuming. have I accidentally deselected something on the summary page that protected it? Thanks, I hope this problem is clear. Sharoo

Okay, went to an older copy of the same document and I am once again able to edit the 26 pages by selecting all sheets without effecting the summary sheet, sure wish I knew how I originally did that.
