on the product_detail.php page, find the following code:
<div class="productDetailWrapper">
      <div class="image">
        <div class="imageWrapper"><img id="ProductImage"  src="imagesupload/<?php echo $row_WADAProducts['ProductImage']; ?>" /></div>
      </div>
      <div class="addToCart">
        <h1 id="WADAPageTitle"><?php echo $row_WADAProducts["ProductName"]; ?></h1>
and change it to:
<div class="productDetailWrapper">
      <div class="addToCart">
        <div class="image">
        <div class="imageWrapper"><img id="ProductImage"  src="imagesupload/<?php echo $row_WADAProducts['ProductImage']; ?>" /></div>
        </div>
        <h1 id="WADAPageTitle"><?php echo $row_WADAProducts["ProductName"]; ?></h1>
then in the css/common.css file, change:
.productDetailWrapper .addToCart {
    background-image: url("../Images/addToCart_bg.png");
    background-position: 50% 100%;
    background-repeat: no-repeat;
    float: right;
    margin-left: 0;
    margin-right: 0;
    min-width: 350px;
    padding: 2px 0 12px 12px;
    width: 370px;
}
to:
.productDetailWrapper .addToCart {
    background-image: url("../Images/addToCart_bg.png");
    background-position: 50% 100%;
    background-repeat: no-repeat;
    float: right;
    margin-left: 0;
    margin-right: 0;
    min-width: 350px;
    padding: 2px 0 12px 12px;
    //width: 370px;
}
