Adding a Listbox

Hi,

I am needing to add a listbox to the code below. That allows a user to select multiple options. Please can someone let me know how?





Option Explicit

Dim m_Prev_QID() As Integer
Dim m_Next_QID() As Integer
Dim m_QID As Integer
Dim m_ItemNo As Integer
Dim m_Question As String
Dim m_Response As String
Dim m_Validation As String
Dim m_PCSOutput As String
Dim m_TotalUniqueQuestions As Integer

Private Sub cmbOptions_Change()

'Get the Option Item Number from the list
If cmbOptions.ListIndex <> -1 Then
m_ItemNo = cmbOptions.ListIndex + 1
m_Response = cmbOptions.Value
cmdNext.Enabled = True
End If

End Sub

Private Sub cmdEnd_Click()

Unload Me

End Sub

Private Sub cmdNext_Click()

If txtInput.Visible Then
Select Case m_Validation
Case "D": 'Date
If Not IsDate(m_Response) Then
MsgBox "Please enter a valid date !", vbCritical
txtInput.SetFocus
Exit Sub
Else
m_Response = CDate(m_Response)
End If

Case "P" 'Percentage
If Not IsNumeric(m_Response) Then
MsgBox "Please enter a valid % !", vbCritical
txtInput.SetFocus
Exit Sub
Else
m_Response = Format(m_Response, "0.00%")
End If

Case "N" 'Numeric - Currency - Term Length - Age etc
If Not IsNumeric(m_Response) Then
MsgBox "Please enter a valid Number !", vbCritical
txtInput.SetFocus
Exit Sub
Else
m_Response = CDbl(m_Response)
End If


Case "T": 'Free Flow Text
m_Response = DoSpellCheck(m_Response)
Case Else: m_Response = DoSpellCheck(m_Response)


End Select

End If

Call SaveData(m_QID, m_Question, m_Response, m_PCSOutput)
m_QID = m_Next_QID(m_ItemNo)

Call Question_Load

cmdNext.Enabled = (m_Response <> "")
CmdPrevQuestion.Enabled = True

End Sub

Private Sub CmdPrevQuestion_Click()


If m_QID = 1 Then
m_QID = 1
