I have this code to display a real-time clock on a worksheet. However if I do
anything else with in the workbook or worksheet such as type in a cell i get
an error message "application defined or error defined error". How do I get
rid of this problem?

Function GetRealDate() As Date

Dim ieApp As Object
Dim i As Long
Dim strTime As String
Dim strHour As String
Dim strMinute As String
Dim strSecond As String
Dim lFirstCom As Long

Const sURL = "http://www.time.gov/timezone.cgi?Central/d/-6"
Const lElement As Long = 36
Const ieREADYSTATE_COMPLETE As Long = 4

Set ieApp = CreateObject("InternetExplorer.Application")

ieApp.navigate sURL

Do
DoEvents
Loop Until ieApp.ReadyState = ieREADYSTATE_COMPLETE

strTime = Left(ieApp.Document.all(lElement).innertext, 40)

'store hour
strHour = Left(strTime, 2)

If Right(strHour, 1) = ":" Then
strHour = Left(strTime, 1)
End If

'store minute
strMinute = Mid(strTime, 4, 2)

'store second
'strSecond = Mid(strTime, 7, 2)

Sheets("Actual").Range("I2").Value = strHour

Sheets("Actual").Range("J2").Value = strMinute

'Range("C1").Value = strSecond

End Function
