Sending data between diagrams through messaging event

I am trying to communicate two processes from different diagrams through messages, I only want to send two data, one directly from one BDM to the other and another from one process variable to the other...
Turns out I can get them to work one at a time, but if I insert two rows into "message content" for some reason the process stops working.
Can somebody help me?

Thanks, i already achieved it.

Can you share more details ? Engine stacktraces ?

Thanks
