I am having trouble with my submit buttons on my expresso store forms. It does not 'recognise' the next attribute in the checkout tag. I.E. I need to click on PLACE YOUR ORDER on my last checkout step to pay for the items, but nothing responds.

```
{exp:store:checkout next="./payu/payu-enterprise-doTransaction-using-soap.php" 
payment_method="Dummy" 
return="store/order/ORDER_HASH" 
<!--secure="yes"--> 
error_handling="inline"}

```

Above is my code for the checkout form. The actual form (not using form tag) is underneath this with control names and values.

When I click on `<input type="submit" name="next" value="PLACE YOUR ORDER" class="button alert" />`, it does not respond at all.

Am I perhaps missing something?
