I am trying to make a system that when sending messages are created in new text boxes, but pressing enter changes all the texts together and I want only the last one created to be changed and the rest remain as previous conversion. I do not know if I explain myself. I leave you an example file with what I achieved. Can someone improve it to make it look like a whatsapp system?
