Each setup block has a properties window that is used to view or change its properties. These
windows are brought up by clicking an icon and then selecting
Edit Properties from the menu

These are cases where it makes sense to use FieldVar blocks.
Using the Add button in the Setup screen (described in the next chapter) we have now attached a
FieldVar block to each measure block:
