[WinCC] How to access valve propierties using VBScripting

[Sandia_Man]

Hi!

I'm having a problem. I draw a valve in my Graphic Designer and also a Rectangle.

I'm trying to do the following:
When the user click on the valve I want the rectangle to be painted in green. When it is clicked again I want the rectangle in red.

I don't know how to access to the valve properties from VBScripting.

If I go to the properties of the valve clicking with the right button of the mouse over the valve and then properties I see under TagAssingment an Atribute called ToggleBit, I think I should try to access to this property but I don't know how...

Any help please???

Thanks a lot!
