voip03 Posted September 3, 2011 Share Posted September 3, 2011 Missing variable A variable's purpose is to store information so that it can be used later. it is a good programming practice to make it crystal clear when a variable is being used for the first time in the program <script type="text/javascript"> function showCD(str) { var xmlhttp; PS. please use the code tag(#) next to post the codes.
