Walla = ORIGIN from the Hindi suffix -vālā ‘doer
(commonly interpreted in the sense [fellow] ),
from Sanskrit pālaka ‘keeper.’

So in short "wala" means it a keeper.
So the question still stands.
What are you talking about?

Or better yet why not comment
regarding weather anything you
have read in this thread has answered
your question.

Imo It's common courtesy to respond
and let others know if your question
has been answered, followed by a
thank you for the effort others have
made in your behalf....
