Bill,

>However, in this case I am using the < OBJECT > HTML tag to instantiate the ActiveX control so it should already be in existence when "MyFunc" is called.

So I guess the question needs to be, "Is the ActiveX control already in existence (fully instantiated) when "MyFunc" is called?". When does MyFunc run and from where is it called? Can you get a good reference to the property in script run from a command button that you click after the page has settled in?

If this is not a timing issue, you might also try referencing the property via the object property of the ActiveX: MyObject.object.property or document.all.MyObject.object.property.
