@reversed_coffee, 
There's nothing "questionable" in the reply Iskra left to you.

You posted something stupid and we're corrected for it, there's no need to leave any aftershock.

 

"I get that we all slip up, and even I do" who are you again????

 

There is no more explanation needed in the code he provided, either. It's self documenting and very easy for anyone to understand.

You're in need of a reality check. If you don't know the answer, don't post it.
