X-Cart forums - Age Calculation for 4.4.x

Based on this thread from the the 4.3.x forum http://forum.x-cart.com/showthread.php?t=53578

My client now has me building another web page. Instead of calculating how old the dog is based on the day/month/year. He now wants to plug in how it will before the dogs are old enough to be delivered.

So then the customers know when the dog will be available for delivery.

I need it to say something like: "Wally will be available for delivery on 3/1/2012"

I tried plugging in this code in the product_details.tpl, but I can't get anything to display, but the Extra Field Values.

Code:

    <tr>

      <td class="property-name">{include file="modules/Age_Calculation/age.tpl"}</td>

    </tr>

I added it in before

Code:

{if $config.Appearance.show_in_stock eq "Y" && $config.General.unlimited_products ne "Y" && $product.distribution eq ""}

Here's the original age.tpl

Code:

Call extra fields via this:

        {$extra_fields.0.field_value}

        {$extra_fields.1.field_value}

        {$extra_fields.2.field_value}
