How Do I total all the variables? in Vb.net - vb.net

Question

How do I add all the variables in VB.net? I do what I was instructed to increment it by placing it outside. Now that I have done it whenever I press the button the output is only 95 and whenever I click multiple times on the picturebox with the incrementation the output is still the same from last time. Nothing is really happening
Private BibimbapQuantity = 1
Private BulgogiQuantity = 1
Private BibimbapPrice As Integer = 45 * BibimbapQuantity
Private BulgogiPrice As Integer = 50 * BulgogiQuantity
Private TotalPriceInt As Integer = BibimbapPrice + BulgogiPrice
Private Sub PictureBox2_Click(sender As Object, e As EventArgs) Handles buttonBibimbap.Click
BibimbapQuantity += 1
Me.DataGridView2.Rows.Add("Bibimbap", "1", BibimbapPrice)
End Sub
Private Sub buttonBulgogi_Click(sender As Object, e As EventArgs) Handles buttonBulgogi.Click
BulgogiQuantity += 1
Me.DataGridView2.Rows.Add("Bulgogi", "1", BulgogiPrice)
End Sub
Private Sub totalPrice_Click(sender As Object, e As EventArgs) Handles totalPrice.Click
End Sub
Private Sub Button1_Click_1(sender As Object, e As EventArgs) Handles Button1.Click
totalPrice.Text = TotalPriceInt
End Sub

Answer 1

You might've written the formula at the top but it's only executed once. You need to execute the formula every time.
Private Sub PictureBox2_Click(sender As Object, e As EventArgs) Handles buttonBibimbap.Click
BibimbapQuantity += 1
BibimbapPrice = 45 * BibimbapQuantity ' <------
Me.DataGridView2.Rows.Add("Bibimbap", "1", BibimbapPrice)
End Sub
You'll need to do the same with the total.
When you are done, put your code in https://codereview.stackexchange.com/ they will help you a lot with refactoring it. Only post on codereview when the code is actually working. They will help you find better way of writing your logic and find possible problems. Great learning opportunity.
