Validity of Cell Contents
For each cell the user can define, in advance, what type of contents will be valid for this cell.
This will make it easier for other users to employ these sheets correctly.
The validity rule is activated when a new value is entered. If an invalid value has already
been inserted into the cell, or if a value is inserted in the cell either with drag and drop or by
copying and pasting, the validity rule will not take effect. To determine and display which
cells contain invalid values, choose Tools > Detective at any time and select the command
Mark Invalid Data.
Additional details about Data Validity can be found in the OpenOffice.org Help.
Using Cell Contents Validity
1. Select the cells upon which to define a new validity rule. Where needed, select multiple
cells by clicking on all respective cells while holding down the Ctrl key.
