Hello:
I wonder what would be the best way to adjust the position of radiobuttons questions on a surveypage?
You can see how my survey looks like in the attached snapshot (it is all in Japanese -- sorry about that!).

My surveypage /caption is centered using the HTML command <center></center> I would like to center my radiobuttons accordingly as well (right now they are left aligned).
Also, I wonder if there is an easy way to control the vertical space between radiobuttons items?

Any help will be greatly appreciated!
Best wishes,
