I have an UDT (`UDT1`) with parameter `Param`. Inside this `UDT1` I have instance of another UDT (`UDT2`) where I want to use the value of `Param`. Lets say I want the value of `Tooltip` to be equal to the value of `Param`.

Something like `{ParentInstanceName.Param}`...?

I found the problem. I have `Param` in `UDT2` too. It overrides `UDT1.Param`. I have to find solution for that... The problem is not solved yet.

Use a different parameter name. "Param" is way to generic to avoid clashes.

Thank you very much. I will try different aproach - to convert `UDT2` to subfolder. It is duplicate of `UDT2`, but I hope it will never go complicated.

Ok. I found a solution. I have to put `{Param}` as value of `UDT2.Param`. If someone else needs such behaviour.
