Hi

Some professionals already has developed the project using menu. In my company, they have given me task to clear the error in that. It is a script file named as "menubarAPI4.js" which is kept inside the folder "menu_script".


The following is the code in this file.

yep ... with that unindented and huge piece of code it is just a pain to try to find anything ... when the IE error messages are confusing you may try it with Firefox and have a look at its error-console or even better install the firebug extension and then trace the error down to a more specific line ... may be firebug gives you better hints for what is going wrong too ...

kind regards
