You must specify a language for content before you submit to Lionbridge, because Lionbridge must know the source and target languages for all translation jobs. The language you specify is the source language for the translation job. The translators translate this content into the target languages.
You can specify a language for an individual item:
You can specify the language for multiple items in the Cart, when you submit them to the Connector, by selecting the Enforce source language check box. For detailed instructions, see Submitting Items in the Cart to the Connector.
Important: To specify a language for content, your site must be set up for multiple languages. If you cannot specify a language, contact your Drupal administrator.
