How to use the TreeControl's active item indent level

Question

I am trying to query the indent level of an item in a TreeControl when I double-click the item.  I have an event structure that captures the double-click event.  In the handler, I read the Active Item:Indent Level property but it returns an error:
Error 1135 occurred at Property Node (arg 1) in Viewer Main.vi
Possible reason(s):
LabVIEW:  The tree control's active item is not valid for this property.
Property Name: Active Item:Indent Level
Does anyone have code to show how to access the indent level for the Active Item?
Thanks,

smercurio_fc,
I may not be using the control properties correctly.  The help for Active Item:Indent Level indicates that it will return the Item Indent value for the active selected tree item.  The indent level indicates the depth in the tree at which the item exists.  For instance, a value of 2 indicates that the item is a Child of a Child of a Root node.  When I try to access the property, I get an error.  I have attached a simple VI (8.2.1) that shows the error and the basics of how I was trying to use it.  Can you point out my error or provide a corrected VI? 
Thank you,
