Hi,
Unfortunately I don't understand Russian, however I asked Google translate for help and obtained the following:
An error in editing tests moodle 2.0.
When you move to different pages of questions top button "transfer" does not work, while the lower button "transfer" works.
Are you using the quiz module? Can you upgrade to Moodle 2.0.3? If you'd prefer help in Russian, please post in the Russian Moodle course.
