Good afternoon.

Is it possible to fill the **tooltip of a tag with the value of another tag**?

I’m trying but it doesn’t work.

**UDT** :

does it not allow you to use the interface (with the treemenu) to create the binding?

For properties like the _ **ToolTip** _, **only parameters** can be accessed. But I need to access another tag of the same UDT.
