Your form element is outside the form so is invalid and ignored by the
browser. What you need is something like:
<tr>
<td valign="top" colspan="3" align="center"><form action="confirm.php"
method="post"><input type="Submit" name="submit" value="Yes">
<INPUT type="hidden" name="testvar" value="<? echo $order_value; ?>" />
</form></td>
</tr>
And similarly for the second form.
But I hope you're only doing this as a test. If you're implementing some kind
on online shopping thing then including the value of goods ordered on a form
and relying on that value when someone posts the form is a VERY BAD thing.
When the form is posted you should always re-calculate the value based on
item and quantity.
