Hi Carl,

Sure,  I've hacked out of my code an example 9removed a few filters
and other elements).  In the specific case that I'm working on the
block element (rt) is an anchor which is valid if it has a name, my
main problem is not being able to increment the ids/names.  I could
see wanting to do this with divs in the future.


<form action="ts" method="post">
<table id="card">
<tr>
<td>
<Div id="rt">
access me
</Div>
</td>
<td>
<div class="clear_left label_vert float_left text">
<input name="day_task" type="text" class="clear_left float_left"
maxlength="45" size="30" />
</div>
</td>
</tr>
<tr>

<td>
<Div id="rt_1">
access me too
</Div>
</td>
<td>
<div class="text">
<input name="day_task_1" type="text" id="day_task_1" />
</div>
</td>
</tr>
<tr>
<td colspan="2">
<input name="num_lines" type="hidden" value="3" />
<div class="submit">
<input name="submit" type="submit" value="Save" />
</div>

</td>
</tr>
</table>
</form>
