This is the issue I'm dealing with. In another post I'm trying to get two checkboxes to insert data two ways (1,1 1,2 and 2,1 2,2). The first Insert Multiple Record SB covers the first set of data, but not the second. My solution was to add a second Insert Multiple Record SB. However, I can no longer access the checkbox form elements from the dropdown list in the Bindings tab.
If this is the way it's supposed to work, then adding a second Insert Multiple Record SB for the same two checkboxes must be wrong.
