In multi-language surveys if you plan to use merge codes to dynamically pull previous answers you'll need to make sure to use the title merge code in order to pull the correct language.
[question("title"), id="3"], [question("piped title")] , and [page("piped title")] - Will all pull the appropriate language in multi-language surveys.
[question("value"), id="3"], [question("piped value")] , and [page("piped value")] - Will all pull the default language in multi-language surveys.
