[ic] Internet Explorer purchase qty problem

[interchange-users@icdevgroup.org (Tony Filipe)]

When a product category has more than one page of products,
the qty purchased is always 1 for the 2nd page and onwards in IE. 

For example:
 Search for 'big balloons' product category gives 3 pages of products.
Adding X-QTY of a balloon on the first page works fine.
Adding X-QTY of a balloon from the 2nd or 3rd pages only adds 1 balloon to
the shopping cart.

 Does anybody know why? Is it a bug with IC?

 The form action is as follows: 

[on-match]
<FORM ACTION="[area nothing]" METHOD=POST>
<input type=hidden name="mv_session_id" value="[data session id]">
<INPUT TYPE=hidden  NAME="mv_action" VALUE="refresh">
<INPUT TYPE=hidden  NAME="mv_separate_items"  VALUE="0">
<INPUT TYPE=hidden  NAME="mv_click" VALUE="munge_quantity">
[/on-match]

The 'add to cart' action is as follows:

<input type=hidden name="mv_oi[item-increment]" value="">
<input type=text name=mv_order_quantity size=2 value="">
<input type=image src="__THEME_IMG_DIR__addtocart.gif"
    onClick="this.form.mv_oi[item-increment].value='[item-code]'" border=0>

Many thanks, 
 Tony
