Show custom link base on product group ID

[caplock]

I'm trying to do some custom coding for the order page and I'm stuck. If anyone know please help me out. Here is what I need to achieve.

 

=== Order page STEP 3 ===

I need to show a specific link on "order.php?step=3" base on certain product group ID. Below is a sample code:

{if $$productinfo.groupid == 2}
<p><a href="custom_page.php">Custom Link</a></p>
{/if}

 

Please let me know what I need to do to achieve this.

 

Thank You

Ok...I just solve my own problem...here is the code if anyone interest.

 

{if $productinfo.groupname eq "Custom Group"}
<p><a href="custom_page.php">Custom Link</a></p>
{/if}

Or

 

{if $gid == 'your product group id here'}<p><a href="custom_page.php">Custom Link</a></p>{/if}
