We have a form that is written in multiple languages and it is public. This means each field has a copy for each language (to change the title/desc), and therefore has a different variable.

What is the best way to report on demographics across multiple submissions in different languages?

My initial though is to write a javascript application to select matching drop down/radio/checkbox indexes from a hidden set of shared variables?

Is this the best method? Has anyone made a multi-language public form with reporting on demographics before?
