Hi Terry,

It seems the code Jim's code (THISFORM.Tree.SelectedItem = THISFORM.Tree.Nodes(1)) is trying to do more than just reference. It's trying to assign a node to the reference, which is usually accomodated with a Nodes(xxx).Selected=.t.

Assigning a node to the SelectedItem property of the tree is perfectly valid (as per the help). Since .SelectedItem is just a reference to a node then it follows that if .SelectedItem is reported as 'not an object' then the culprit is actually the node which it is attempting to reference. Maybe in Jim's case the Node(3) which he expects to be the SelectedItem is the problem
