       ByVal e As System.EventArgs) Handles submitButton.Click

        DisplaySales()

        ' clear TextBox input

        itemText.Clear()
        mondayTextBox.Clear()
        tuesdayTextBox.Clear()

        Dim monday As Decimal
        Dim tuesday As Decimal
        Dim wednesday As Decimal
        Dim thursday As Decimal
        Dim friday As Decimal
        Dim total As Decimal
        Dim itemtotal As Decimal


        'not sure if these are working or even doing nething sorry i don't know much about this program

        ' i know it needs a lot of working on

        tuesday = CDec(Val(tuesdayTextBox.Text))
        wednesday = CDec(Val(wednesdayTextBox.Text))

Help with WHAT? You have explained what you WANT to do but not what your code IS or IS NOT doing.

well i want my code to do that... my code actually doesn't do anything right now i type in my inputs and click then nothing happens.

Have you tried stepping through your code? Does your Click event handler execute?

well when i click on the button the text boxes clear and it puts the headers in the list box but nothing else

How do you expect this code:
        monday = CDec(Val(mondayTextBox.Text))
        tuesday = CDec(Val(tuesdayTextBox.Text))
        wednesday = CDec(Val(wednesdayTextBox.Text))
        thursday = CDec(Val(thursdayTextBox.Text))
        friday = CDec(Val(fridayTextBox.Text))
to return anything other then 0 when you call this code directly before it:
        itemText.Clear()
        mondayTextBox.Clear()
        tuesdayTextBox.Clear()
        wednesdayTextBox.Clear()
        thursdayTextBox.Clear()
        fridayTextBox.Clear()

And, in fact, how does this not throw an InputString exeception? Trying to convert an empty string to a Decimal will most certainly throw that error.

i know sorry for not using posting rules but i have till tonight to finish this here's my updated code it still doesn't input the sales values but it does input the item name


================================================== =
Public Class SalesReportForm

   Dim itemCount As Integer = 0
    Dim itemNames(0 To 9) As String
    Dim itemsales(,) As String = New String(0 To 9, 0 To 6) {}
    Dim count As Integer = 1
    Dim monday As String
    Dim names As String
    Dim itemtotal As Double
    Dim total As Integer


   ' handles Submit Button's Click event
   Private Sub submitButton_Click(ByVal sender As System.Object, _
      ByVal e As System.EventArgs) Handles submitButton.Click

        If count = 1 Then
            DisplaySales()
        End If



        names = itemTextBox.Text
        monday = mondayTextBox.Text


        outputListBox.Items.Add(names)
        itemsales(itemCount, 1) = (monday)
        itemsales(itemCount, 2) = tuesdayTextBox.Text
        itemsales(itemCount, 3) = wednesdayTextBox.Text
        itemsales(itemCount, 4) = thursdayTextBox.Text
        itemsales(itemCount, 5) = fridayTextBox.Text

        itemCount += 1

        tuesdayTextBox.Clear()
        mondayTextBox.Clear()
        wednesdayTextBox.Clear()
        thursdayTextBox.Clear()
        fridayTextBox.Clear()
        itemTextBox.Clear()
        Do While count < itemCount
            itemtotal += Convert.ToDouble(itemsales(itemCount, 1))
            count += 1
        Loop




        If count > 10 Then
            submitButton.Enabled = False
        End If


        ' check if 10 items have been entered
        If itemCount = 10 Then
            submitButton.Enabled = False
        End If
    End Sub ' submitButton_Click

   Sub DisplaySales()

      ' clear the ListBox


        If count = 1 Then
            ' create a header for the ListBox
            outputListBox.Items.Add("Name" & ControlChars.Tab & _
               ControlChars.Tab & "Mon." & ControlChars.Tab & "Tues." & _
               ControlChars.Tab & "Wed." & ControlChars.Tab & "Thur." & _
               ControlChars.Tab & "Fri." & ControlChars.Tab & "Total")
        End If
        Dim output As String
    End Sub ' DisplaySales
End Class ' SalesReportForm
================================================== =================

You never add the data in your Array to the list box. The only time you ever write data to the list box is here:
   Sub DisplaySales()

      ' clear the ListBox


        If count = 1 Then
            ' create a header for the ListBox
            outputListBox.Items.Add("Name" & ControlChars.Tab & _
               ControlChars.Tab & "Mon." & ControlChars.Tab & "Tues." & _
               ControlChars.Tab & "Wed." & ControlChars.Tab & "Thur." & _
               ControlChars.Tab & "Fri." & ControlChars.Tab & "Total")
        End If
        Dim output As String
    End Sub ' DisplaySales

And this statement:
Dim output as String is unnecssary. You don't do anything with it, its declared at the end of your method, and is out of scope for all the other methods in your class.
