I have a webpage when it finished on the left bottom there's a warning says:Done, but with errors on the page. I double click it and it told me:

Line:628
Char:100
Error: Expected ')'
Code: 0
URL:.....

I knew Fiddler is a good tool to debug. I download it and try to debug. The line IE told me I just can't find anything that's missing ')'

Can someone tell me how to debug this?

IE may be interpreting line numbers differently than you expect. Firebug is probably a better tool for helping debug this type of problem.

Fiddler is good at capturing what goes across the stream. It's like paring a hammer and a wrench. Each is the right tool for a specific job.

If using IE8, hit F12 to bring up the debugger. You can start debugging and have it show you exactly where your error is occurring.

The open ( is probably occurring several lines before the missing ).
