Help!how to animate a line from one pt. to one pt. (MX)?

i can’t make the ■■■■ line white… grrr…

i have

this.lineStyle(1,0x000000,100);

grrr…

edit: duh… that’d be black anyways, but i’ve been messing wit it some more and i still can’t get it white… =/

yet another edit: ok i got it to be white now… but it wont go in front of a background i made… even tho i have the layer with the actionscript on top.
