You have got to be kidding me.....

 

^ ^ I agree with this

 

Not just that, but I am working on a script that uses this code, so where did you get this from...

 

It was for a client I was working with. We had problems with this code

 

Well from what I can see, there seems to be no issue with the javascript code.

What issue did you see?
