I'm trying to create a form having 3 checkboxes. People can check or leave each line unchecked (it's not a required field in other words). And I need to store that information, check or unchecked on Salesforce, and the field type doesn't really matter to me on Salesforce. For my example, I used 3 dropdown fields on Salesforce.
My problem is that it is impossible to define unchecked values on Act-On. As a result, if I uncheck a box and submit the form, Salesforce will keep the previous data stored. So people will subscribe to checkbox 1 for example, they will uncheck it X months later, but salesforce will still mention that Checkbox 1 is checked, just because Act-On isn't pushing any data on form submission.
Does anybody have an alternative to do what I'm trying to do? By the way, I'm simply trying to create a subscription management system, because the Act-On default subscription management system is really bad, limited and ineffective.
