Using a Segment Variable to display all products with the same title in a Playa field

Question

I've created a segment variable for brands that shows in the URL. I want to write an {if} statement that looks at the URL segment for brand and then brings back the products that match the playa field for brand. (ie. If the URL segment says BEAM I want to show all BEAM products that have been selected from the Playa filed). How do I go about doing this? Any suggestions?

Here's a very basic example. This doesn't include the code to only show products with the same name as {segment_6}. Any suggestions? I hope this helps.

<!--I only want to show the code below if segment_6 has something-->
{if segment_6 != ""}  
    {exp:store:search channel="products"}
        {exp:store:product entry_id="{entry_id}"}

                <!--I want all of this code to display the products that match segment_6 with the Playa field brand selected in an entry-->
                {exp:playa:children field="brand"}
                    <h1>{title}</h1>
                {/exp:playa:children}

                <!--this should also display based on the brand in the playa field above-->                                                     
                {product_description}
            {product_image}                                         

        {/exp:store:product}        
    {/exp:store:search}
{/if}

This is a shot in the dark as I'm still confused on how you have everything configured.

You could just pass the {entry_id} in the {exp:playa:children} playa tag and that would give you all related products that that entry created:

{exp:playa:children entry_id="{entry_id}" field="brand"}
     {title}
{/exp:playa:children}
