How have you got the Join node configured? You might be better to use key/value pairs then they will already be identified by topic contents.

Make sure the two messages coming in have different topics, then feed the output of the join into a debug node. What do you see?

@Colin  
Can you give an example of join with key / value with the next node, which is the function node to separate these values?
