https://mydomain/*cart/refreshcart*Are the asterisks supposed to be wildcards? That's actually not supported in hook_menu().If your goal is to put the asterisks into the URL itself, that's a really bad idea (I don't even think it's a valid URL).If they're not actually in the code, and you just put them there to make the paths stand out for us - sorry, just ignore me then. Besides clearing the cache, you might also make sure that uc_cart_block() is getting the right number of arguments, and that the path to uc_cart.module is correct. (The 'file' path in hook_menu() is relative to your module, not to Drupal's root directory.) That's all I can think of...-Karl.
