<p>I, for one, fail to parse "why coming channel concept while explaining method concept" as a question.</p>
<p>That's absolutely okay that English is not your native language but still we need to bring your question up to certain form for it to be comprehensible.</p>
<p>Try not to cram many words in a single sentence.
It's OK to have multiple sentences stating what you have/see
and then another one—asking a question based on the stated facts.</p></pre>vamsc08: <pre><p>need help</p></pre>
