How to use metafield for product variant redirect in Dawn theme?

[Gumf]

So I have a product will 10 variants but I have also had to create separate listings for each variant (clients request) so that on a collection page you can view all variations. However, is there a way to redirect the variation product listing to the main product listing which contains the variants?

I have created a global url metafield called Redirecturl but can't figure out how to implement it. I tried adding the following code to the theme.liquid file but it didn't work:

    {%- if product[handle].metafields.global.Redirecturl -%}
    <script>
         window.location = "{{ product[handle].metafields.global.Redirecturl }}";
     </script>
{%- endif -%}

I am using the theme - Dawn.

That would be great if you could. Thanks

I would prefer to discuss it here so others can benefit from the solution. Thanks

you don't need to add handle 
product already contains hadnle


 {%- if product.metafields.global.Redirecturl -%}
    <script>
         window.location = "{{ product.metafields.global.Redirecturl }}";
     </script>
{%- endif -%}

This was spot on thank you! I just needed to tweak the .global to .custom too.

Thank you so much!
