This usually happens when you have a Javascript error and you have Visual C++ (or any other debugger isntalled in your computer). The best way to help you is that you send us a snippet of the code. What's in line 1 of your code anyways?
here is the code.I am not sure what and where it means as "line 1 syntax error"(I replace some < with [ in order that the code may be display in text.)thanks.
