How to change slider widget price range text and "Go" label in KickStart Commerce?
Below is a work around. See if it works :


Create a file custom_string_overrides.inc  inside your custom module folder and add the below code:


$conf['locale_custom_strings_en'][''] = array(
  'Go' => 'Add replacement here',
  'range from' => 'Add replacement here',
);


Add the below code to settings.php


include DRUPAL_ROOT . '/path-to-module/custom_string_overrides.inc';

The above trick does the string replacement and texts will be replaced where ever they appear. As I mentioned, this is just a workaround.
