Hi Cheryl,
We looked into this also, and can't get it to work. In a smart campaign's flow area, we added a change score flow action, defined the score to be changed as "Lead Score", then added "={{lead.Demographic Score}}" in the change amount field. This would not save. When we removed the equal sign, the system threw an error that only my tokens can be used in score fields.
Can you please confirm we aren't missing something?
We can do this in SFDC, but would prefer to do it in Marketo to prevent periods of inconsistency due to integration delays, deleted records in SFDC and leads v. contacts.
Thanks,
Chris
