Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you please explain what you are trying to do with your code, what is it for?
You have a pot and a temperature sensor, please list all the cases you want to program into your code and the output responses.
This sounds like a switch.. case type solution.
Tom.... 
while(condition) {
// At this point condition is true
while(condition) {
statement(s);
}
//If we are here, condition is false
statement(s);
}
so instead of using while loops i tried with if nested loops and the code was working fine ......
thanks to all those who replied and sorry for replying late.
