Hello
Why is there some code with a hard coded length? e.g. components/com_virtuemart/views/cart/tmpl/default_pricelist.php
<input type="text"
onblur="check<?php echo $step?>(this);"
onclick="check<?php echo $step?>(this);"
onchange="check<?php echo $step?>(this);"
onsubmit="check<?php echo $step?>(this);"
title="<?php echo JText::_('COM_VIRTUEMART_CART_UPDATE') ?>" class="quantity-input js-recalculate" size="3" maxlength="4" name="quantity" value="<?php echo $prow->quantity ?>" />
checks should be done on the quantity range in the price table and certainly not hardcoded into the script.
Regards
