Is there any way I can create surveys in my local languages of Sri Lanka (Sinhala & Tamil)?

Can't I use a font writer or something & type text in other languages? I dont mind submit & next buttons being in English....

You can have your form in another language by following this guide: http://www.jotform.com/help/298-How-to-make-your-forms-multilingual. The non-English characters can be added in the labels and text, but that will depend on the keyboard you are using.

Do let us know if that works.
