ReadvalueList error

ReadvalueList error was created by info@software2000.it
Good morning,
i am trying to read a value via the readvaluelist method
I am attaching the code used, the succeeded property is truer, there are no messages in exception nor in errormessage, but when I try to assign a variable to the .value it gives me an incorrect type error, I tested with vartype but it would seem that the property .Value does not exist on its own, what can I test further to understand?
Thank you
Code:
ReadArgumentCk=CreateObject("OpcLabs.EasyOpc.UA.OperationModel.UAReadArguments")
ReadArgumentCK.EndpointDescriptor.UrlString=alltrim(URI)
ReadArgumentCk.NodeDescriptor.NodeId.ExpandedText=alltrim(nodo)+alltrim(memonic)
ReadArgumentsCheck.Add(ReadArgumentCk)
ValueresultCheck=oClient.ReadValueList(ReadArgumentsCheck)
resultCheck=ValueresultCheck.Item[0]
errore=ValueresultCheck.Item[0].Exception
errore1=ValueresultCheck.Item[0].ErrorMessage
if resultCheck.Succeeded
valore=resultCheck.Value ////////error Function argument value , type or count is invalid
(((((((
endif
Please help me
