An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll
Additional information: Syntax error in INSERT INTO statement

What I have tried:

private void LoanDetails()
{
   foreach (DataGridViewRow row in dataGridView1.Rows)
   {
      String connstring = ConfigurationManager.ConnectionStrings["FincorpData"].ConnectionString;
      string cmdstring = "insert into installment (InstallmentNumber, LoanNumber, InstallmentDate, LoanAmount, PaymentStatus,) VALUES (@InstallmentNumber, @LoanNumber3, @InstallmentDate, @LoanAmount, @PaymentStatus)";

      using (OleDbConnection con = new OleDbConnection(connstring))
      {
         using (OleDbCommand cmd = new OleDbCommand(cmdstring, con))
         {
            con.Open();

            cmd.Parameters.AddWithValue("@InstallmentNumber", row.Cells["SrNo"].Value);
            cmd.Parameters.AddWithValue("@LoanNumber3", row.Cells["LoanNumber"].Value);
            cmd.Parameters.AddWithValue("@InstallmentDate", row.Cells["Date"].Value);
            cmd.Parameters.AddWithValue("@LoanAmount", row.Cells["Installment"].Value);
            cmd.Parameters.AddWithValue("@PaymentStatus", row.Cells["Status"].Value);

            cmd.ExecuteNonQuery();
            con.Close();
         }
      }
   }
}
