Accessing AdvSmoothProgressBar properties

I'm sorry but this is probably trivial but I am struggling to work out how to do it...

I want to set some values for properties in the SmoothProgressBar (e.g. Direction to pbdVertical).  When I use the following code it doesn't compile ('undelcared identifier: 'pbdVertical') 


I know that I am missing something basic here but any help would be greatly appreciated!

Please add the unit GDIPFill to your uses list.
