As acid_kewpie pointed out, this isn't the way to use a forum, you need to use clear and concise English. (You can be excused if you're not a fluent English speaker or not a native English speaker).

I try to get on the forum at least twice a day to check on answers to the questions I've asked and to check on answers that I've given. When the problem is solved, you need to be sure to give the solution that worked and mark the thread as solved.
