Checkboxes and Custom Data Objects

Question

I'm trying to create a form with a list of checkboxes based on customers' interests - there's 8 in all and they can select multiple options.
What I want to do is to create shared lists for each option which will serve as a segment members for future mailings.
I also need to hold the data for that individual together so if I ever need to, I can go in and say 'Well, Joe Bloggs here is interested in X, Y and Z so I'll put him into campaigns A and B'.
Are Custom Data objects the way to go? I've had a go at creating one and mapping it, but I don't know what to do with these checkboxes!!
Thanks!!

Answer 1

For the shared list, simply use the "Add to Shared Contact List" processing step for your form and make it conditional on the box being checked. You'll need 8 of these steps, one for each option.
For keeping the data, I would use a Custom Data Object. Create a new CDO set with a field for the email address and one for each of your checkboxes (plus whatever other info you want, of course.) And then use the "Update Custom Data Object - With Custom Values" processing step. You can set this step to add a "yes" or "on" or whatever else you'd like to the appropriate field in the CDO. Again, make this step conditional on the checkbox being checked in your form. Again, you'll need to create 8 of these steps, but once you get the first one done, the others should go quicker.
PS, I kept typing "from" instead of "form." Argh.
