I procrastinate like you would believe! I have this homework project due tomorrow and I keep getting errors specifically with "index" do I have to declare it somewhere or add a specific item form the Toolbox on my form? I'm stuck help!!

Code:
Public Class Form1
Dim Wname(10) As String
Dim Hours(10) As Integer
Dim Wages(10) As Integer
Dim Wpay(10) As Integer Private index As Integer = 0
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
Dim nind As Integer = 0
Dim ind, total As Integer
Dim fmtStr As String = "{0,-10} {1,20}"

For ind = 0 To index
total += Wpay(ind)
Next
  lstSummary.Items.Add(String.Format(fmtStr, "Worker Name", "Payment"))
For nind = 0 To index - 1
  lstSummary.Items.Add(String.Format(fmtStr, Wname(nind), Wpay(nind)))
Next
  lstSummary.Items.Add("Total Workers Processed :" & index)
  lstSummary.Items.Add("Total Wages Payed :" & total)
End Sub
Private Sub btnEnter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnter.Click
Wname(index) = txtName.Text
Hours(index) = CInt(txtHours.Text)
Wages(index) = CInt(txtWage.Text)
If Hours(index) > 40 Then
Wpay(index) = 1.5 * Wages(index) * Hours(index)
Else Wpay(index) = Hours(index) * Wages(index)
End If
  index += 1
  txtName.Clear()
  txtHours.Clear()
  txtWage.Clear()
  txtName.Focus()
End Sub
End Class
