as per your your form design i thing you want to calculate the balance of item.
so for this your logic will be balance_item = total_purchase - (sales_item + return_item)
but u did like this balance_item = balance_item + return_item
so as per my coercion thing about your logic... is this perfect...

{
c = int.Parse(TextBox3.Text) + int.Parse(TextBox4.Text);
TextBox3.Text = Convert.ToString(c);
}
we declare as c is not = zero then y we declare as c=zero.
now also it throw error sir
