Thank you , It works !
but why I have Browserdetesct is undefined Error in IE?
Can you help me with it as well?
Tom BeckCommented:
Likely there is a some client side script being called because of code you have included or are referencing in an external file that is trying to do a browser detect but it is failing. It may be failing in all browsers but you are only seeing it in IE. In Firefox for example, if you go to the Error Console, do you see the same error listed? You can do a text search of your code and all included script files for the word browserdetect and find the source of the error.
