Active Directory VBS Scripting, getting blank or no value for "cn" attribute

I am writing a script to write the computer name ("CN") attribute of computer accounts in an OU of Active Directory into description field of the computer account but I am just getting blank or no value for CN attribute. I had attached the image of the code execution results (which shows blank value – i have four computers with the different computer name in the specified OU). Please help to check my code (I have hidden the Active Directory path which shows my company details) and advise me where I did I made a mistake. Thanks.

Set objConnection = CreateObject("ADODB.Connection")

Set objCommand = CreateObject("ADODB.Command")

objConnection.Provider = "ADsDSOObject"

objConnection.Open "Active Directory Provider"

Set objCommand.ActiveConnection = objConnection

objCommand.Properties("Page Size") = 3000

objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE

‘Start Operation
Set objRecordSet = objCommand.Execute

‘Go to the first record (AD account) in the specified OU

‘continue operation until the last record (AD Account) in the specified OU

‘set string named strUserPath to "AdsPath" value of a AD accounts’ properties, AdsPath = Active Directory Path
strUserPath = objRecordSet.Fields("AdsPath").Value

‘Get the AD object and assign it to objEntry

set objEntry=GetObject(strUserPath)

set valuename=objEntry.Get("cn")

strmessage = "The computer name is :"&valuename

wscript.Echo("The computer name is :"&valuename)

     objEntry.Description = strmessage
