serialGSM error in program

i try to run send sms program in arduino 1.5.2 simulator it get error.
like

sketch_mar08d.ino:3:10: error: #include expects "FILENAME" or
sketch_mar08d:4: error: 'SerialGSM' does not name a type
sketch_mar08d.ino: In function 'void setup()':
sketch_mar08d:9: error: 'cell' was not declared in this scope
sketch_mar08d.ino: In function 'void sendSMS()':
sketch_mar08d:14: error: 'cell' was not declared in this scope
sketch_mar08d.ino:3:10: error: #include expects "FILENAME" or
sketch_mar08d:4: error: 'SerialGSM' does not name a type

sketch_mar08d:9: error: 'cell' was not declared in this scope
sketch_mar08d.ino: In function 'void sendSMS()':
sketch_mar08d:14: error: 'cell' was not declared in this scope

and also attach program sample.

gsmmessage.ino (482 Bytes)

I didn't know there was a simulator, but the IDE also gives this error

gsmmessage.cpp:2:23: error: SerialGSM.h: No such file or directory

when I try to compile your sketch.
Where did you download the "SerialGSM" library from, and where did you put it?
Did you restart the IDE after installation?

The first error message seems to be related to this piece of code:

#include <SerialGSM.h>
#include 
SerialGSM cell(2,3);

Hopefully, the reason is obvious. I suggest you fix that error and try again.
