Safari 5 not recognizing submit button on forms.

I have a table with a form on each row:


<form method="post" action="index.php">
<input type="hidden" name="pk itemstore" value="10535">
<input type="hidden" name="pk_items" value="2171">



<tr>
<td>


Peanut Butter, Natural,

<label for="aisle"> Aisle:<input name="aisle" type="number" size="2" min="0" max="1000" value="10"></label>



<label for="brand"> Brand:<input type="text" size="6" name="brand" value="365"/></label>

<input name="crud_mode" type="submit" class="button01"value="Update & Buy">
<input name="crud_mode" type="submit" class="button01"value="Update">


$0.72 cheaper at BJ-Dedham

<input name="crud_mode" type="submit" class="button01"value="Item Store Delete">
</td>
<td align="right"
<label for="pkg_qty"> Pkg Qty:<input name="pkg_qty"type="number" size="5" min="0" value="2"></label>



<label for="pkg_size"> Pkg Size:<input name="pkg_size" type="number" size="5" min="0" value="2.25"></label>


<label for="pkg_price"> Pkg Price:<input name="pkg_price" type="number" size="5" min="0" value="3.69"></label>


<label for="pkg_shipping"> Shipping:<input name="pkg_shipping" type="number" size="5" min="0" value="0.00"></label>



<label for="pkg_tax"> Tax:<input name="pkg_tax" type="number" size="5" min="0" value="0.00"></label>


<label for="tax_rate"> Tax Rate:<input name="tax_rate" type="number" size="5" min="0" value="0.000"></label>

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







However in Safari 5, the browser will not respond when I click on any of the submit buttons, when I check the console in the Web Inspector I see the following error messages.


-----------

<form> cannot act as a container inside <tbody> without disrupting the table. The children of the <form> will be placed inside the <tbody> instead.
index.php:1559

<input> is not allowed inside <tbody>. Inserting <input> before the <table> instead.


---------------

I have a similar problem with the Chrome beta. Is this a problem with latest version of webkit, or do I need to change something relative to tables and forms?
