Change a text field to a select list?

[MJP]

I'm trying to change a text field to a select list (to list quantities such as 1,2,3,4 etc..)

I can change this to a select list but it's not working right. Anyone have any idea how to do this?

(this code is from Product Multi contrib)

 

$lc_text = '<input type="text" name="add_id['.$number_of_products.']" value="0" size="1">';

$lc_text .= '<input type="hidden" name="products_id['.$number_of_products.']" value="'.$listing['products_id'].'">';
