AAC Changing purchase buttons, shop.lua Znote

[Jpstafe]

Hi

How do i change purchase buttons from shop.php?

<input type="submit" value="  PURCHASE  "  class="needconfirmation" data-item-name="<?php echo $offers['description']; ?>" data-item-cost="<?php echo $offers['points']; ?>">

I want it to look like in the picture below, i have examples obout how I have adapted it in the other buttons.

<input type="submit" name="new" value="Add Image" div class="BigButton btn" style="margin: 0 5px;float: right;background-image:url(layout/tibia_img/sbutton.gif) ">

<div class="BigButton btn" style="margin: 0 5px;display: inline-block;background-image:url(layout/tibia_img/sbutton.gif)">
                                                Back
<input type="Submit" value="Search" div class="BigButton btn" style="background: url(layout/tibia_img/sbutton.gif); width:135px;height:25px;border: 0 none;" border="0"></td>

But instead buttons look like this. I have changed all the buttons in the website, except for these ones that is giving me headache.
