Can anyone rectify this error and help me with this code . Please !!!!!!!!!!!!!!!!!!!!!!
The error is "blue is not defined in this scope".
Below is code along with it's library.
Please correct it and reply.

What error?
You need to post the error message.
And don't post your email address in a public Forum unless you enjoy being flooded with SPAM.
Nobody here is going to send you a response using email. You have to come back and read the Forum.

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?
blue is what you are calling your BT channel, however you need to use Software Serial library if you are going to use it with a UNO and not use pin0 and pin1 of the serial monitor.
This may help;
If a Mega, use one of the other hardware UARTs.
Thanks.. Tom..

I would have expected an error like "SHIFT KEY/CAPS LOCK FAILURE DETECED."

Seems fairly clear. It's telling you that you are trying to use something called blue, as in blue.begin(9600). But you have never defined anything called blue. We can only guess what blue is supposed be and where and how it might be connected. The compiler won't guess, you have to tell it.
