Just add &quantity=2 at the end of the Add to Cart button's href= URL, like so:



<a href="https://www.e-junkie.com/ecom/gb.php?c=cart&i=XXXXXX&cl=41615&ejc=2&quantity=2" target="ejejc" class="ec_ejc_thkbx" onClick="javascript:return EJEJC_lc(this);"><img src="http://www.e-junkie.com/ej/ejadd_to_cart.gif" border="0" alt="Add to Cart"/></a>

Could you provide the URL of a page where this is happening, so we could examine that? Quantity shown in the cart should never be blank; it always defaults to 1 unless an &quantity= parameter in the button URL specifies otherwise.

Oh, now I see. It appears you're using customized button code to let buyers enter a quantity on your page before they add an item to their cart. Normally, buyers would edit quantity in the cart itself after they add an item, so that's where I got confused. Adding a value="" attribute to your quantity <input> tag would prefill that field with whatever value you specify, e.g.:



<input type="text" name="quantity" size="2" value="2">
