I tries to debug an error in IE 8 developer tools. It is showing that the error as follows,
'length' is null or not an object JScript - script block, line 21 character 19
But i could not locate the script block, line 21 character 19. So do anybody have any idea on how to locate this error?
You can try to enable debuging mode my click on start debug, when error occur, IE will locate the block for you
