Hi Sam,

You have to:
-Define VAR_X as input of the node. Something like this:
 http://dcalca.files.wordpress.com/2011/05/input1.png http://dcalca.files.wordpress.com/2011/05/input1.png
You give it a name to use inside the workItem.

-You can get the variable from work item parameters.
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
                    workItem.getParameter("VAR_X")
 ...
}


- Define VAR_X as output of the node.
It is similar to the input

- Put this variable in the result map
Map<String, Object> results = new HashMap<String, Object>();
                                                  results.put("VAR_X", var)

You can see that you are not directly accessing to the global variables.. you have inputs and outputs of each task..
