Error while creating object using description.create object in VB script

[SarodeGirish]

'Create a description for browser

Code:

Set oBrowser = Description.Create
oBrowser("micclass").Value = "Browser"

'Get all browsers
Set allBrowser = Desktop.ChildObjects(oBrowser)

Dim i, iCount

iCount = allBrowser.Count - 1

For i = 0 To iCount
    
allBrowser(i).Close
  
Next

After executing the above code I am getting the error as "Object required 'Description'
