Grey Out Issue

[FSKI]

I just took over a new job and they have a database in Excel 2007 Compatibility Mode that they want a sheet protected. However, the sheet protect and a myriad of other functions are greyed out. I have tried everything to get back these functions, but they seem to be locked out. The old system admin says he thinks he did something before, but doesn't remember what.

Any thoughts or ideas?

Thank you!!!
