Sorry to be so blunt, but we have [ code ][ /code ] tags (without the spaces) that preserve formatting and syntax highlight code. This may make your code more readable and hence encourage more help.

But to answer your question...

What I would like to know is can you pull two arrays from one form

Yes. What part exactly are you stuck with?

Also being blunt, but an assignment should be researched by YOU, not solution provided by us! How ya gonna learn...?

I am not sure how to code the arrays properly, I can make it work if I have only one array but I really think I messed up with the 2nd one.
