If oneName does not refer to a Range, oneName.RefersTo range will error.
The OnError Resume Next protects against that.
let oneName ReferTo the formula ="x"
On Error Resume Next
If oneName.RefersToRange.Row <> 2 Then :Rem code errors, resume with next line
Rem Do Nothing: Rem don't delete this name
Else: Rem equivilant to "GoTo End If"
oneName.Delete: Rem will execute iff .RefersTo does not error and .Row<>2
End If
On Error Goto 0
If the Else branch were more complicated, I might have reset On Error Goto 0 inside the branches.
You are right, the block If construction is not needed, so I could have done it all in one line (wrapped in Error handling)
