I have added the snapshot here.as this node is not yet published i cant show the page to you to you.as you can see the add to cart form is not shown here properly

I didnt get u the admin access.. as this is the live site containing customer data

do u really need admin access to see the page code.

I can see that the template file commerce-cart-add-to-cart-form.tpl.php has bwlow code

i have marked in bold the code which is having issue, here it is limiting the code to work only with variation 'product'. Please let me know what do chnage here to make it work for all product types

<?php
 $product = commerce_product_load((int)$form['product_id']['#value']);
 $query = new EntityFieldQuery;
 $result = $query->entityCondition('entity_type', 'node', '=')
->propertyCondition('type', 'product')
->fieldCondition('field_product_ref', 'product_id', (int)$form['product_id']['#value'], '=')
->range(0, 1)->execute();
  
 $nids = array();
 foreach ($result['node'] as $node) {
$nids[] = $node->nid;
 }
 $node = node_load((int)$nids[0]);
?>
