<tr><td>Naam:</td><td colspan='4'><input type="text" id="naam" name="naam" value="" onkeyup="showName(this.value)">
<br> <input type='submit' name='zoek' value='zoek'></td></tr>
</form>
<div id='txtName' style='100%; padding:5px; border:1px solid #000000'></div>
<tr><td>Naam:</td><td colspan='4'><input type="text" id="naam" name="naam" value="" onkeyup="showName(this.value)">
