How to bring some lines on top of others in flash?

Question

Today I finally started working on some animations, and after drawing a sketch for the animation background i decided to work it out in flash, using the line tool, and paint bucket mostly. Anyhow, I got this weird problem that I cant bring lines on top of others..well actually I don't know how, so thats why I'm asking this. For more detail on what I meant by ''bringing lines on top of others'' check out this screenshot:

-I made circles around the parts where one line is on top of another, also I tried making a new line on top of those, to cover them, but unfortunately it didn't help. :(

Please help me find a solution to this problem.

Answer 1

I'm not sure whether the lines that show on top are already a symbol or not, if yes, right click on 1 of them and arrange, send to back/send backward.
