CMMN Exit Sentries and passing variables

Hay Guys

I have the following CMMN. It works well and everything seems to be active or disabled when it needs to be. The problem is this way I cant seem to pass the variables back into the Parent BPMN (The token never moves from the start of the CMMN Call process). I have tried many different permutations? I cant seem to get it right. Any suggestions?

Thank you
