I am trying to follow KB Article 001225 which outlines how you go about creating multiple sharepoint list items from a repeating field / group within Infopath.  I have created the activity slots, but the second part describes using the instance data property:

In the event where you want to use the data that was read from the repeating node, use the Instance Data property found in the Workflow Context Browser as shown below.  If there are three repeating nodes, for example, three slots will be created at runtime.  The Instance Data property on each slot will contain the value for each item in the repeating node, from top to bottom

Im not sure how i use this to create a sharepoint list item with data relevant to that node- can anybody help?
