Registered users put in specific usergroup depending on the profile field selected

[Renada]

Hi everyone,

Not sure the title makes much sense but I'll try to explain here.

I would like people that register on my site to automatically go into a specific usergroup depending on which of the specified profile fields they check.

i.e. I have a checkbox profile field with 3 options: A - B - C

If users check A I would like them to automatically go into usergroup 1, if they check B then usergroup 2 and checking C would put them in usergroup 3.

Could anyone please tell me how I would do this?

Thanks in advance

Regards,
Renada
