I'm trying to get the name of the campaign where the person opened the form and save it in the supplemental table of the form. I saw that it has the campaignname() function but I didn't know how to use it. the form call in the body of the email:
$personalizedform('test_form', 'EMAIL_ADDRESS_',concat(CAMPAIGN_NAME=campaignname()))$
and the hidden field in the form:
<input type="hidden" name="CAMPAIGN_NAME" value="$CAMPAIGN_NAME$">
i managed to figure out how to do this and it was really dumb of me not to notice it but i can just use campaign.name in the form call
