Discussion answered question

how to remove discussion???

Why would you want to? Solved problems should be left here for others with similar problems to search for.

I must agree. They’re left on the board for all of us to read and learn.

The very best way to end the discussion is for you to REPLY that you received the answer that you were after.
Then, the susequent reader will know that no reply is needed.

Too many posts are left up in the air without the o.p. responding in the end.
