Selenium c# coding : driver.FindElement(By.Id("navHHome")).Click();
            driver.FindElement(By.LinkText("Canon")).Click();


            driver.FindElement(By.Id("searchBrand")).SendKeys("Canon AP" + Keys.Enter);
            driver.FindElement(By.Id("pListSearch")).SendKeys("AP 01" + Keys.Enter);


I am getting an error

Could any one tell me if this is rightly coded?

Thanks
