check all in Coupon

Is there possible, to make button or something, to select all products? in Coupon?

I know about this one, but this works in Catalog=>products ,
I need something like that in Customers=>Coupon

Q,

I downloaded the checkallboxes module from the unbannable.com site. From the site, it states it is compatible with 1.4x, but in the readme.txt file, 1.4x was not listed.

I tried following the instructions, but didn't get very far.

In step 2, I could not find the file, nor a file that contained the search string.

2) Add script to layout.tpl:
a) Edit: admin/view/template/common/layout.tpl
b) FIND:
---------------------
<script type="text/javascript" src="view/javascript/jquery/tab.js"></script>
---------------------
c) AFTER, ADD:
---------------------
<script type="text/javascript" src="view/javascript/jquery/checkall.js"></script>
---------------------

Perhaps it is not compatible with 1.4x or am I missing the obvious?


Thank you for your help,
JQ
