X-Cart forums - SKU and variants on products.tpl

I have products with variants. I input a SKU for the main product details and then create separate SKUs for each variant. I'm getting different SKU reults showing, dependiong on which view I'm in:

-When I view the product page it gives me the main SKU I entered under product details i.e. NOT the variant SKU

-When I view a category or search listing it displays the SKU of the first variant I set up.

How do I get it so that both views display the product details SKU as opposed to the first product variant code?

Here's what I have in products/product templates:

customer/main/products.tpl:

Code:

{$lng.lbl_sku}: {$products[product].productcode}

customer/main/product.tpl:

Code:

{$lng.lbl_sku}: {$product.productcode}

I've tried putting the product.tpl code into products.tpl but it only shows the label.

Any ideas?

Thanks
