in the studio editor, I added the display of the name and amount of the opportunity to the list of leads
the corresponding columns appeared in the table, but the cells are empty
how can I solve this problem?
If I understand correctly, that’s not going to work. Once you “convert” a lead you create a “Contact” where the person information is stored and an “Opportunity” where the deal information is stored. The “lead” is irrelevant at that point. It’s only related to the converted contact, Opportunity and Account.
If you had previously populated the “Opportunity Amount” in the Lead, it should still be there, but it will not grab any updated “Opportunity Amount” from the “Opportunity” after it is converted.
