Messed Up Robot Main.vi by changing something in Begin.vi?

[stopyourself]

I have not edited robot main.vi at all. This problem has occurred on two separate programs, so I know I'm doing something wrong, I just don't know what.

The error I'm seeing when building my code says
"Items with errors:
Robot Main.vi
Details Display Dialog.vi
Not Found Dialog.vi"

With Robot Main.vi, the connection stemming from Begin.vi is broken; the error says the code is trying to wire together two different data types (cluster of three elements to boolean). For Dialog.vi, it says that the function is not supported for the current target.

I'm very new to LabView; what could I have changed in the Begin.vi that would have caused this? Attached is Begin.vi
