I am having a contest in which the user enters some info into a custom field on a landing page. They can enter it twice if they share out the link to the landing page. I have it set up so that after it's been verified that they shared it on FB they get redirected to another landing page so that they can put in another entry. Unfortunately, when they put their email in again and put the info in the 2nd custom field, the first custom field is erased. Has anyone done anything like this before?
