[RESOLVED] Datagridview Average

This one should be fairly easy (I hope)...

Code:

---

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim tot As Integer = 0
        For i As Integer = 0 To DataGridView1.RowCount - 1
            If DataGridView1.Rows(i).Cells(1).Value = txtName.Text Then
                tot += DataGridView1.Rows(i).Cells(5).Value
            End If
        Next
        If tot = 0 Then
            MsgBox("No Records Found")
        End If
        txtTotal.Text = tot
    End Sub

What I need help with is how to expand this code to have it average the total sum this code calculates by the number of entries it added. Basically I need it to count how many different entries it added to get that total and use that number to average.

You guys have been a big help so far, thanks and I hope I can get along on my own for a while once this is done!

First up, why make your code less clear by using "tot" instead of "total" just to save yourself two keystrokes? If the extra two characters is too much work then why not use "sum" instead?

As for the question, you already know how to do it because you're already basically doing it. In your code, you declare 'tot', initialise it to zero and then add a value to it inside the loop. You can do exactly the same thing to calculate a count. The only difference would be that you would add 1 to it inside the loop.

As for "tot" instead of "total", I'm just learning and I found that in another loop forum. Makes sense, I'll try to start using better practices. I am at the point right now when I read someone else's code it makes sense and I can usually repeat it once I've done it, but just coming up with it on the spot I usually get it about half right and spend hours of frustration and reading forums trying everything but the right way... then when I finally get it to do what I want, I find out there's an easy way to make an error that I now have to code against :)

I don't know if it's "correct" but it works... if there's a better/safer way please let me know.

Code:

Dim total As Integer = 0
        Dim total2 As Integer = 0
        For i As Integer = 0 To DataDataGridView.RowCount - 1
            If IsNumeric(DataDataGridView.Rows(i).Cells(1).Value) Then
                If Not IsDBNull(DataDataGridView.Rows(i).Cells(6).Value) Then
                    If DataDataGridView.Rows(i).Cells(1).Value = txtName.text Then
                        total += DataDataGridView.Rows(i).Cells(6).Value
                        total2 += 1
                    End If
                End If
            End If

        Next
        If total2 > 0 Then
            Dim text As Integer
            text = total / total2
            Label1.Text = text
        End If

        If Val(Label1.Text) < Val(TextBox3.Text) Then
            With Label1
                .ForeColor = Color.Red
            End With
        Else : Label1.ForeColor = Color.Black
        End If

Ah, I see you edited your post after I first looked at it. It seems better, but 'total2' is a terrible variable name. You should use names that indicate the purpose. It's a count so call it 'count' or something more specific.
