Double posting is against forum rules. I have moved your previous thread into the appropriate forum section.

Please try to have patience. Everyone here has lives outside of the forum. You should wait at least 24 hours before "bumping" a post. Not to mention that a LOT of stuff has been covered in the past. You might try putting two of those words you typed already together. One starts with a "v" and another with a "b".
