Player button triggers and conditions

Can anyone help me figure out how to make this file work?  I can get the layers triggers to work, but I am having trouble with the next button conditions.

The user shouldn't be advance in the course until they have typed in their names and the narration has completed.

I have tried adding a T/F variable to the next button to require narration to be completed, but then the next button doesn't work.

I also tried adding a T/F variable to the "sound"...that didn't work.

Is there a limit to the number of conditions that can be put on a player button?
