>>> Type: Bugfix
>>>
>>> Bugtracker references: http://bugs.typo3.org/view.php?id=9553
>>>
>>> Branches: TYPO3_4-1, TYPO3_4-2, trunk
>>>
>>> Problem:
>>> Script jsfunc.validateform.js uses variable "a" in function split()
>>> without declaration. And if html page has an element with id="a" it
>>> causes script error then as IE thinks that "a" is an object.
>>>
>>> Solution:
>>> To fix it variable should be declared: "var a;"
>>
>> There are more local variables not declared with "var". Are there no
>> problems with them?
>>

> Yes, you are right, I firstly encountered it with "a" variable and did 
> not checked others. Now I've cheked all of them and found few other vars 
> affected too. If there is a <div> with such id name then js error will 
> be casted as IE confuses it with document objects. So I have fixed these 
> vars too and here is updated patch.

Still my +1 after reading
