Adobe Sign form "Create an agreement from library template ..." allows to specify up to 7 recipients.
The issue is when you want to make the number of recipients dynamic (I want to specify recipients in sharepoint list: sometimes you have two signers and sometimes 3 or 5).
To specify dynamic signer e-mail from sharepoint "Rep_Op2" column I was trying those expressions:
I'm trying to do the same thing right now and have tried both of the methods you describe above. Am hoping you get a solution!
The solution that works currently is to check how many signers You have, create switch statement based on that variable and program as many different blocks calling adobe sign. Braindead, repetitive, error-prone, but works.
Bummer. I was afraid that would be the answer. Certainly not ideal.
