In the English version:
Format|Cells|Protection tab (not Security)

Hi Barbara,

Just to explain further. Select the first cell you wish to allow
'user input' in. Then hold down control and click on all the
other 'user input' cells. Once they are all selected let go of
the control button and go to FormatCellsSecurity tab
and 'uncheck' the locked option and OK out.

Now when you apply protection you will be able to change
only those cells that have been unlocked.

HTH
