Bold word Quantity in products order page

Customers seem to miss the quantity box on the order form, and are ordering one, where they meant more. I know, I know, how do they miss it in all the other following pages? Don't know.

I would like to bold it, and ideally add Please Choose: prior to it.

using Developer tool, I think this is the file. includes/templates/mycarthere/templates/tpl_product_info_display.php

but not sure where, or if this is correct.

Still searching for a solution for this. About 5 customers a day, are ordering just 1, when they really want a quantity. Mystery to me as to why. But cannot find place/file to edit. Maybe a .css issue. not sure where it would be there either.

Since that's the only text in the Add to Cart box, you could do something like this, adding the red part, in the stylesheet:

#cartAdd {
float: right;
text-align: center;
margin: 1em;
border: 1px solid #000000;
padding: 1em;
color: #ff0000;
font-weight: 800;
}

You could change the text in english.php, here:

Line #366 : define('PRODUCTS_ORDER_QTY_TEXT','Add to Cart: ');

Thank you!!! both of those did the trick.
