Mailchimp groups / Conditions

Hi there,

I'm trying to achieve some things with mailchimp groups but can't seem to work it out.

I have several groups in one mailchimp list and i want to be able to let the customer choose with jotform fields and hidden mailchimp groups. I'm trying to do this with conditions. What i also want is one default selected option in the mailchimp group but as soon as I select an option in jotform the default selection is overruled.

When I use "copy value from multiple fields" the selections are messed up. It seems only one condtion based field works ok to update mailchimp groups.

Is there any way to get this to work with some advanced tools maybe?

I setup my mail chimp account to have 3 groups in 1 list:

Then I integrated my form and it added the groups as radio buttons on my form:

You can change the Department by using a condition like so:

Here we type the full name of the group to set.

You can see this example demo working here:
