Tooltipduration syntax

I’m trying to change the time my tool tip stays on the screen to 10 seconds. I’ve added the line
line below : “toolManager.toolTipDuration”: 10000
However, the diagram is not displayed. Can someone advise how to properly do this? Thanks
myDiagram =
$(go.Diagram, “myDiagramDiv”, // must be the ID or reference to div
initialAutoScale: go.Diagram.UniformToFill,
padding: 10,
contentAlignment: go.Spot.Center,
layout: $(go.ForceDirectedLayout, { defaultSpringLength: 10 }),
maxSelectionCount: 2
“toolManager.toolTipDuration”: 10000

You’re missing a comma to separate the key: value pairs of the options Object argument to go.GraphObject.make.

Geez, thanks Walter. Too many late nights for me.
