como corrijo este error

[fmontesma]

The Case or Event structure does not have anything wired to the output tunnel in one or more cases. Since only one frame of the structure is executed, every frame must assign values to all the outputs. Right-click the tunnel and select Use Default If Unwired to relax this requirement.

Como dice el error, asegurate de que todos tus tuneles (como el booleano de la derecha del case structure) tengan un valor valido.

Mas informacion: Missing assignment to tunnel
