using autofilter and sort, while sheet is protected
 

Hi,

I would like to protect a sheet but still make sure that people, without the
password to unprotect the sheet, can use the sort function and the autofilter
function.

I use: [Tools Protection Protect sheet] In the option: 'allow all users
of this worksheet to: ... I put the mark (v) for:
- select locked sells
- select unlocked cells
- sort
- use autofilter

When I then close and open the sheet its impossible (without unprotecting
the sheet) to use the autofilter of sort function.

Does somebody know why?

Thanks in advance.
