Put In Error Handling In Case The Format Of The Page Changes Or The Internet Page Is Unavailable

I have some code that parses an html table. I want to put in error handling in case the format of the page changes or the internet page is unavailable. I am testing without an internet connection and the run time error is not being branched off to the error handler and is fatally ending the macro. This is true also if I raise an error manually.

Private Sub ParseInjuryPage()
On Error Goto ErrorHandl
Dim strPage As String
Dim webIE As SHDocVw.InternetExplorer
Dim myURL As String
Dim tableBeg As Long
Dim tableEnd As Long
Dim RowBeg As Long
Dim rowEnd As Long
Dim cellBeg As Long
Dim cellEnd As Long
Dim strBeg As Long
Dim strEnd As Long
Dim myCell As Range
Dim rowNum As Integer
With Sheets("INJ")
Set myCell = .Range("A2")
.Range("A:F").Value = vbNullString
rowNum = 2
Set webIE = New SHDocVw.InternetExplorer
myURL = "http://www.sportsline.com/nfl/injuries"
webIE.Navigate myURL
Do Until webIE.ReadyState = READYSTATE_COMPLETE
DoEvents
Loop
strPage = webIE.Document.body.innerhtml...................................
