Typo on first line. A semicolon ";" should be replaced with a comma ",".
Also, breaking the var declaration onto seperate lines improves readablility.

Original, with misplaceed ";":
var v1=50; v2=100, v3=150, v4=200, v5=2, v6=250;

suggested improvement:
var v1=50, 
    v2=100, 
    v3=150, 
    v4=200, 
    v5=2, 
    v6=250;
