Compile error:

Hi,

I just started using access this May so I apologize in advance for my basic questions.

My database is currently made of several forms, each form having its own table. I have linked each form with a previous and next button. I have also created a combo box for which each option (a specific form) will lead to the opening of the desired form and the closing of the current form. I have written the following code:

Private Sub Combo475_Click()
On Error GoTo Err_Combo475_Click:

Dim stDocName As String
Dim stLinkCriteria As String
DoCmd.Close
If (Combo475 = 1) Then
stDocName = "Background A"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 2) Then
stDocName = "Background B"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 3) Then
stDocName = "Background C"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 4) Then
stDocName = "Background D"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 5) Then
stDocName = "Background E"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 6) Then
stDocName = "Background F"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 7) Then
stDocName = "Background G"
DoCmd.OpenForm stDocName, , , stLinkCriteria
Else
If (Combo475 = 8) Then
stDocName = "Background H"
DoCmd.OpenForm stDocName, , , stLinkCriteria
End If
End If
End If
End If
End If
End If
End If
End If

Exit_Combo475_Click:
Exit Sub

Err_Combo_475_Click:
MsgBox Err.Description
Resume Exit_Combo475_Click:

End Sub

Problem: I keep getting a "Compile error: label not defined" message and the second line:
On Error GoTo Err_Combo475_Click:
is highlighted when this error message pops up.

Can someone tell me what is wrong with this line?

Thanks!

I may be remembering wrong, but I don't think you want to include the colon in this line
