Thread: javascript var if

hey guys, need some help.

I have the following

================
var countrycode="ZA"
//Rate per km (number)
var rateperkm=20;
//Minimum fare (number)

var minimum_distance=30;
//LESS THEN ZAR250//

var minimum_fare=250;
//Currrency Symbol
var currencysymbol="ZAR";
//Avoid motorways / highways? true/false
var avoidHighways=false;
//Avoid toll roads? true/false
var avoidTolls=false;
//Show summary? true/false
var showsummary=false;
//Show Route Map
var showroutemap=true;
//Disclaimer text
=======

how do I add a "var if" to the minimum distance?

I tried this -> if (minimum_distance >400) rateperkm=10; {}

which says if kms is greater then 400km then charge 10, instead of 20.

but it doesnt work.

any help would be appreciated.

Javascript is not the same as java.
