I am working on a program and I need to add  all fields for a running total. Here is the code

 Private Sub Totals()
        Dim pintCount As Integer
        Dim pdblGrossTotal As Double
        Dim pdblWithholding As Double
        Dim pdblNetPay As Double
        Dim dtEmployees As DataTable

        For pintCount = 0 To dtEmployees.Rows.Count - 1
            pdblGrossTotal = dtEmployees.Rows(pintCount).Item("fldGrossPay")
            txtGross.Text = pdblGrossTotal.ToString

        For pintCount = 0 To dtEmployees.Rows.Count - 1
            pdblWithholding = dtEmployees.Rows(pintCount).Item("fldWithholding")
            txtWithholding.Text = pdblWithholding.ToString

        For pintCount = 0 To dtEmployees.Rows.Count - 1
            pdblNetPay = dtEmployees.Rows(pintCount).Item("fldNetPay")
            txtNetPay.Text = pdblNetPay.ToString

    End Sub

*** I am getting an error on the line              -     pdblGrossTotal = dtEmployees.Rows(pintCount).Item("fldGrossPay")

The error is " options strict on disallows implicit conversions from system objects to double.  How do I convert a system object to a double?

also if you want a running total youll have to do this

pdblGrossTotal = pdblGrossTotal + CDbl(dtEmployees.Rows(pintCount).Item("fldGrossPay"))

otherwise its just going to grab the last value

try the whole thing in the same loop
like this
        For pintCount = 0 To dtEmployees.Rows.Count - 1
               pdblGrossTotal =  pdblGrossTotal  + CDbl(dtEmployees.Rows(pintCount).Item("fldGrossPay"))
              pdblWithholding = pdblWithholding  + CDbl(dtEmployees.Rows(pintCount).Item("fldWithholding"))
              pdblNetPay = pdblNetPay + CDbl(dtEmployees.Rows(pintCount).Item("fldNetPay"))
         Next pintCount

         txtGross.Text = pdblGrossTotal
         txtWithholding.Text = pdblWithholding
         txtNetPay.Text = pdblNetPay
