Parse Error

Hi there everyone,

I'm trying to run an if statement and inside that have other if's, but it keeps 
telling me I have a parse error on the first if in the if statement (The second 
if down).  Can anyone see what i'm doing wrong?

if ($packages == "1")(

if ($airporttransfer == "car")(
$airporttransfer2 = "12.00");
if ($airporttransfer == "bus")(
$airporttransfer2 = "10.00");
if ($airporttransfer == "none")(
$airporttransfer2 = "0.00");

);

Thanks for your help :-)

Chris
