Barry,
Thank you! I was missing the "Edit" step.
I was able to get things working. But the lashup is continuing to give trouble. I played around with it today with both the handheld and the i-pad. I've come to the conclusion that the problem is not the TUI, the Wi-Fi, i-pad, or the hand held remote. The problem lies in one of the engines. The lashup will startup normally with all the usual sounds. Horn, bell, couplers, and lights all work. But neither unit will move. I have them on the same track, separated by several inches. If I shut the lashup down, and call up the individual engines, one will always respond correctly, including moving. The other is a crap shoot. Sometimes things work, sometimes they don't. Anything to look at before I contact a MTH service center? The engine is under warranty.
