setlayeroptional

   Hi
I am am having some problems with layers.
I have the following in my program
Result = .NewOptionalContentGroup "1"
LayerID = .GetOptionalContentGroupID (1)
Result = .SetOptionalContentGroupVisible(LayerID, 0)
Result = .SetLayerOptional(LayerID)
It works OK until the .SetLayerOptional statement which returns a 0, The OptionalContentGroupID parameter was not valid.
The ID must be valid as the .SetOptionalContentGroupVisible statement works fine.
I have also tried using the ID returned by .NewOptionalContentGroup but get the same results.
All help much appreciated.
