How to use fiddler to debug?

Question

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?

Answer 1

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