I'm creating an event that allows people to invite co-workers. So, we want to know how many additional guests, he/she is going to invite. I'll have a field in the form asking for that, but I'm not sure how to map this? I don't want this to be sync to SFDC because this will be just one time event and there's no value to capture that information in SFDC. I just want to be able to pull the data from Marketo to get a count of participants. Is there a way to do this?
