Thanks Charles ... I don't understand the B grade?
As per EE help:
"....Grading at Experts Exchange is not like school. It's more like the "10-point Must" system in professional boxing; in other words, an answer is worth an A, unless it doesn't resolve your issue. If it requires you to do a little more research, or figure out one more piece of code, then it's worth a B. If you think it's not worth a B, the custom is to offer the Experts an opportunity to earn a better grade.
Giving a higher grade has no impact on your Available Points...."

I was under the impression that my answer did resolve the issue when you accepted the answer (of course, unless your keyboard was DOA in which case, nothing I proposed would have worked).
If you feel you have graded a solution incorrectly, click the Request Attention button and the Moderators will change it for you. If another member disputes the grade you have given, you will be asked to explain your reasoning; please respond to those requests....
