Oracle database errors with vb.net - sql

Question

I am tasked with making a simple GUI based database viewer. The database is hosted on our schools ftp server we must use visual basic and for the most part I've got it working I can search, view, and add to the database, but editing an existing record is giving me problems.
When I attempt to update the record I get a ora-00904 error invalid identifier when not using a colon (:) in where portion of the query and an ora-01008 not variables bound with a colon (:). We so far have only really used sqldeveloper and as a final project we were asked to use Visual Basic but we never covered anything like this in class so its a challenge I suppose.
PS: I only have that portion commented out so that I could view the error.

Dim strCity As String = ""
Dim strState As String = ""
Dim intZip As Integer = 0
Dim datDateSignedUp As Date
Dim intCustomerNumber As Integer = 0
Try

txtState.Text = ""
txtZip.Clear()
txtDateSignedUp.Clear()
txtCustomerNumber.Clear()
'txtCustomerEmail.Select()
txtCustomerEmail.Enabled = True
txtLastName.Enabled = True
txtFirstName.Enabled = True
txtAddress.Enabled = True
txtCity.Enabled = True
txtState.Enabled = True
txtZip.Enabled = True
txtDateSignedUp.Enabled = True
txtCustomerNumber.Enabled = True
'Catch ex As Exception
' MessageBox.Show("An error occurred while attempting to add a new record.", "Error")
Finally
conn.Close()
txtCustomerEmail.Select()
End Try
End Sub

You are missing Customer# from your parameter list.
