Sum of Gridview colum that has a dynamically added row.

Before I would ask my nth question, I would like to thank everybody for your help. As an aspiring c# programmer your valued response is really a big help.

I'm trying to make a cashiering system. For the details I'm using a gridview with a rows that are dynamically added. Now, I want to get the sum of the column "Amount Paid" but all the codes that I tried failed. Please note that this is a data entry. To make my self clear, I'm attaching an image and my code behind. Thanks in advance for your help.

Below is my code:

decimal amount = 0;
protected void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
decimal amount = Convert.ToDecimal(e.Row.Cells[12].FindControl("txtNetAmountReceived").ToString());
amount += Convert.ToDecimal(amount);
}
if (e.Row.RowType == DataControlRowType.Footer)
{
Label lblamount = (Label)e.Row.FindControl("lblAmountPaid");
NetPremium.Value = totalPaid.ToString("N2");
}
}

I think the problem is with the amount variable, you had declared 2 times with the same name, change the variable to identical will reaolve the issue.
