How use another php file in contact form

Hi

I've created an alternative layout in templates\hot_furniturestore\html\com_contact\contact\prueba.php (in the same place that default.php) and I've modified the parameter as shown in the image.

But all still works same, I can see the map too.

thanks

in components\com_contact\views\contact\tmpl\ there are 6 .php files and one .xml try to copy all of them to override folder replacing "default_" in their name with something else like "map_"
