is it possable to have 2 loops in a script???? :-?
What do you mean?
Like this?:
void loop(){
while(someContidion){
executeSomeCode;
}
while(someOtherContidion){
executeSomeOtherCode;
}
}
Not to be picky but Arduino programs should be referred to as 'sketch' or 'program' 
erm..... but idk the reasons.
O__o

Can you tell us more about what you're trying to accomplish?
probably pwnz0r means about 2 threads, that is not possible, however you can emulate this behavior
yup.
