Is it the Code, the Hardware or my Ignorance?

John,
Thank you, I appreciate the input and mini-lesson.

Two Questions:
Would the receiver's pulse keep the Right Turn, Left Turn, and Reverse from occurring but still give me Forward and Left-turn?

The code snippets you sent, should they go in any particular section of my current Sketch?

Sorry, I'm a total noob, and still learning.

Thank you again.
