Thats worked on 50% of the input fields but not on these 2:
<textarea name="Item" rows="4" class="" id="Item" value="<?php echo(ValidatedField("clientareaupdate_502","Item")) ?>" style="float:left;width:248px;"></textarea>
<textarea name="Description" rows="4" class="" id="Description" value="<?php echo(ValidatedField("clientareaupdate_502","Description")) ?>" style="float:left;width:248px;"></textarea>
