Hi there,
We offer a number of services, and a contact can be interested in multiple services at the same time. To reflect that, I created a custom property of the multiple checkboxes field type: Services of interest: A, B, and C. Each of these services has its own web page and a lead capture form. I’m trying to configure the forms so they update the ‘Services of interest’ field. I added the ‘Services of interest’ field to each form and made it hidden. For the form on Service A page, I made A prechecked and so on. The problem with this solution is that when a contact fills out the form on the Service A page, the contact’s ‘Services of interest’ field gets updated and checks ‘A’. When that same contact submits the form on Service B page, B is checked and A is unchecked. Is there a way to avoid overwriting the existing value?
TLDR version: Is it possible to make a form pass values that update a multiple checkbox field by appending rather than overwriting the existing values?
I welcome other solutions that achieve the goal: keeping track of the multiple services each contact is interested in, and updating the field using forms.
Thanks
