<p class="Paragraph">The <help:link Id="66827" xmlns:help="http://openoffice.org/2000/help">validity rules</help:link> restrict the input of numbers, dates, time values and text to certain values. However, it is possible to enter invalid values (if the Stop action is not selected) or copy invalid values into the cells. When you assign a validity rule, existing values in a cell will not be modified.</p>
