[SOLVED] cannot get check-box checked by default

Thanks for your reply and explanation, I thought the value had to be 1 rather than zero in order to set the default?
FYI: The field is only in the profile editor and not on the registration.

Could you see how my screenshots are not configured correctly to set this multiple checkbox with just one value to checked by default after a user's registration?

There is no 1 and 0 value for a multicheckbox. The value is whatever you set it to. It does not get set to 0 when you uncheck all multicheckbox values. It's simply set to empty. As this is to establish a default for a field that is not shown on registration you don't need the condition at all so removing the condition should resolve your issue since it's not valid anyway.

sorry for the long learning curve but I get it now and it works as I wish... thanks for helping out!
