Help with TreeView runtime error

[keithb]

What causes this intermittent runtime error?

Microsoft Jscript Runtime Error: 'ct100_TreeView1_Data is undefined.

When the error occurs, the following section of code is highlighted:
on MouseOver="TreeView_HoverNode(ct100_TreeView1_Data, this"

I looked for a missing property related to Hovering, but nothing jumps out
at me. Any ideas?

Thanks,

Keith
