<pre><b><u>FYI:</b></u> Whatever question you may have, you'll never get a correct answer with this RUBBISH from the other person who responded, so SIMPLY IGNORE it, AS USUAL!! {{{cross(system(2b=f,b-11=3(f-11)))}}}
In addition, you didn't bother to ask a question, and so, why should I even try to give you an answer!
