Can anyone tell me why the “LeadSourceId” URL parameter only works when it is typed exaclty: “LeadSourceId”?
For example, this works by assigning an appropriate Lead Source to a new contact:
But this does not work (Lead Source field is blank):
www.grabthisfreebie.com/opt-in-page?leadsourceid=111 (all lower case)
(These are examples only)
What the heck???
