adding signatures

[Emily325736701dja]

I have sent and received a document for an e-signature (person A). I need to send it to someone else (person B)  now for their signature. When I do this Adobe says the document is unsupported.  

How do I do this, as person A must sign first and person B is after.

You need to add two signature fields (in advance), or use Adobe Sign.
