How to ask a question in an existing thread

Today morning I asked a question about classic tags. I was asked to ask my problem in an existing theread. Thats ok. I searched for relevant topics and found one with Subject - "Classic Tag Handler Question" . The problem is I do not know how to ask my problem in that topic.
The only button which I think I can use is "POST REPLY" but then it might look like I am answering some question and not asking mine and so am scared that I mught not get any replies to my question.

I don't know how to proceed and am stuck. The question is trivial but important.

Any help will be greatly appreciated.

Simran you created two topics for the same problem - this and this so you were asked to continue discussions in one of them. Two topics in two separate forums for the same problem is not a good idea, read this...

And why on earth would it be in SCWCD? Moving to Ranch Office.

Thanks Ankit . Now I know what you mean. When I submitted my question and checked if
it was showing in the questions list it was not there. So I submitted the Question again and that is the mistake I made . I should have waited for sometime. Thanks once again
