You are refering to a non-existing object. It means that you have to create a cursor before you can read its properties.

To create a cursor, follow the steps listed under Adding Cursors to Graphs in the LabVIEW Help.

Also, if you have more that one cursor in your graph remember to set the "Active cursor" property to the index of the cursor you need to access before reading its position or performing any other operation on it.
