This Xpath works fine when i am passing static id i.e
driver.findElementByXPath("//tr[@id='Billable Client']/td/input").getAttribute("id");
but It doesnt work when I passed variable i.e
String Level3KeyCase0Trimmed = "Billable Client";
driver.findElementByXPath("//tr[@id='"+Level3KeyCase0Trimmed+"']/td/input").getAttribute("id");
tried by removing '...' single qoutes as well
