for any project i am attempting to add an increase trolley button around the featured items template. From things i read in the documentation you can easily use echo $addtocart but this may nothing echo $form_addtocart doesn't give results either.

Any Help?

//Number of featured products to show per row
$featured_per_row = 3;
//Set the cell width
$cellwidth = intval( (100 / $featured_per_row) );

if( empty( $featured_products )) {
    return; // Do nothing, if there are no Featured!
}

echo "<h3 style='font-size:220%'>".$VM_LANG->_('VM_FEATURED_PRODUCT')."</h3>";
foreach( $featured_products as $featured ) {
    ?>
    <div style="float:left;width:<?php echo $cellwidth ?>%;text-align:top;padding:0px;" >
    <div class="browseProductContent2">
         <a title="<?php echo $featured["product_name"] ?>" href="<?php $sess->purl(URL."index.php?option=com_virtuemart&amp;page=shop.product_details&amp;flypage=".$featured["flypage"]."&amp;product_id=".$featured["product_id"]) ?>"> 
            <h4><?php echo $featured["product_name"] ?></h4></a>
            <?php echo $featured['product_price'] ?><br />

            <?php
            if ( $featured["product_thumb"] ) { ?>

                <a title="<?php echo $featured["product_name"] ?>" href="<?php $sess->purl(URL."index.php?option=com_virtuemart&amp;page=shop.product_details&amp;flypage=".$featured["flypage"]."&amp;product_id=".$featured["product_id"]) ?>"> 
                <?php echo ps_product::image_tag( $featured["product_thumb"], "class=\"browseProductImage\" border=\"0\" alt=\"".$featured["product_name"]."\"");
                ?></a><br /><br/>

            <?php
            }?>
            <?php echo $featured['addtocart'] ?>
            <?php echo $featured['product_s_desc'] ?>



    </div>
    </div>
    <?php
    // Do we need to close the current row now?
    if ($iCol == $featured_per_row) { // If the number of products per row has been reached
        echo "<br style=\"clear:both;\" />\n";
        $iCol = 1;
    }
    else {
        $iCol++;
    }
}

?>
<br style="clear:both;" />
