I'm trying to embed views like this:
views_embed_view('articles_list', 'block_1', '11+13');
If I type 11 in arguments, it does take the argument. It works good if I preview the view and enter '11+13' in "Preview with contextual filters" field... But if I write '11+13' in the views_embed_view() function, it just takes the value of 11. How can I make it work and take both values: 11 and 13?
