Brittany,
Follow Section 14 for dialogue. When the user name is not in print you will need to add a TN that they have been added.
The boxes moving from the right and left is a visual effect identifying the change in speaker but will be solved by following braille formats. Each dialogue in 1-3 with the speaker’s name before.
I am not sure about the boxes. If you are doing each one, or each section. Be careful of excessive boxes. Sometimes the format change from 3-1 to 1-3 can be sufficient.
Hope this helps,
Connie
