grey "ok" button, when sharing folder

[adatok2]

The sharing folder function have worked perfectly until now, but now I can't add shared folder, because my "ok" button is always grey: (I use the hungarian version, but you can see)
Guest additions are installed. XP sp3 on XP sp3. What is the problem?

It's solved, but I dont know, why does it work so?

If there is a special character (for example "space") in the path than you can't press "ok).
