Offhand, your code looks fine.
Can you send a small, self-contained example?

I have an int I intend to broadcast from root (rank==(FIELD=0)).
int winner
if (rank == FIELD) {
winner = something;}
MPI_Barrier(MPI_COMM_WORLD);
MPI_Bcast(&winner, 1, MPI_INT, FIELD, MPI_COMM_WORLD);
MPI_Barrier(MPI_COMM_WORLD);if (rank != FIELD) {
