You should be aware that it’s customary to assign the Solution tag to the post that is the first to identify the issue and offer a solution. In this case, you took the information provided to you and marked your own post as the Solution.
If everybody did that then no matter how much assistance they received, the solution would always appear to come from the same person who asked the question. It would appear that everyone ultimately solves their own problem … and if that were true then they wouldn’t need help in the first place. That’s why the Solution tag is assigned to whoever’s post actually provided the solution.
