Error commenting after "If...then"

[EricE]

This code has a comment at the end of the "If...then" line.

    If strTempValue = "C" Then ' Celsius
      strCommand = "DEGC"
    Else 'Fahrenheit
      strCommand = "DEGF"
    End If

This results in an error message being displayed
"Block warning: End of IF block found, but no matching beginning."

The error message will go away if the trailing comment is removed.

    If strTempValue = "C" Then  
      strCommand = "DEGC"
    Else 'Fahrenheit
      strCommand = "DEGF"
    End If

Should we simply avoid placing a comment on the same line after the "then" keyword?
