keeping out of trouble
Adding a second Sequence Beam lets your program do more but also increases the number of ways that things can go wrong. Using multiple Sequence Beams affects almost every aspect of NXT-G programming, including variables, data wires, My Blocks, and program flow. This is an advanced programming technique that can allow you to write some incredible programs but can also cause a lot of confusion. Here are some tips to help you avoid the most common problems:
Use a second Sequence Beam only when it’s really necessary. If you can find a solution to your problem that requires only one Sequence Beam, then you’re usually better off avoiding the added complexity.
Go slow when editing the program. The IDE tends to get confused much easier ...
