New Post: Translation of texts

I don't know wheter this is the right forum for my question, but may be someone knows the answer.

For my webshop I translated a lot of texts from english to dutch. There is one remaining.

A user is not logged in and orders something in my webshop. Then the users checks out and before the address collector appers, the user has to log in. And in that screen the user can switch between "I do not have an acoount" and "I have an account".

Does anyone know where I can translate this?
