Format of the initialization string does not conform to specficiation starting at index 46

I am trying to open an SQL database and write a record.  Here is the error message I am getting.

An unhandled exception of type 'System.ArgumentException' occurred in system.data.dll

Additional information: Format of the initialization string does not conform to specification starting at index 46.


Here is the code.

'Get Math Objective Info

            Dim m As Int32
            Dim midx As Integer = 1
            Dim mathObjNumbersArray(60) As String
            For m = 1 To 101 Step 2
                mathObjNumbersArray(midx) = Mid(mathObjNumbers, m, 2)
                midx += 1
            Next

            Dim m1 As Int32
            Dim midx2 As Integer = 1
            Dim mathItemCorrectRespArray(60) As String
            For m1 = 1 To 101 Step 2
                mathItemCorrectRespArray(midx2) = Mid(mathItemCorrectResp, m1, 1)
                midx2 += 1
            Next

                mathStudentRespArray(midx3) = Mid(mathStudentResp, m2, 2)
                midx3 += 1

                Dim objCommand2 As SqlCommand = New SqlCommand
                objCommand2.Connection = objConnection2

                Dim m4 As Int32
                For m4 = 1 To 60
                    objCommand2.CommandText = "Insert Into itemAnalysisDetail " _
                                & "(admDate, studentId, teacherId, objectiveNumber, itemCorrectResp, studentResp) " & _

                    objConnection2.Open()
                    objCommand2.ExecuteNonQuery()
                    objConnection2.Close()
                Next

            Catch ex As Exception
                MsgBox(ex.Message)

            End Try



Any help is greatly appreciated..
