rollseyes* I don't need you to comment on my post. Obviously if I don't have a solution or work if I don't know where to begin. Also, has anyone told you not to say anything if you don't have anything nice to say? I don'e know about you but I was raised in the South. Instead of commenting and wasting your time, you could have easily just passed the question. There's no need to be rude. I don't need you to do my homework, just guidance. If you can only offer rude comments, just don't comment at all.You were told on your 1st post to show your work.
Homework not done here.
