Hello..i am new to the arduino world.. I just want to know , right now i'm working on data logging to pachube.com using GPRS .For the moment I only want to submit temperature data to my pachube.com , and I read about this at http://seeedstudio.com/wiki/GPRS_Shield#Uploading_Sensor_Data_to_Pachube.com_using_GPRS ..I try adjust the codes there , as I want to submit only one data per time I will not use any SD card to store the data,so I adjust the code like below:
my equipment is:
1 lm35
1 arduino duemilanove
1 SIM900 GSM/GPRS MODULE
really, it is a simple project,but ,I'm new to this,and I cant detect any error to the following code,so please guys I am eager to know, why I cant get any reading at my pachube account.The serial terminal said my data succesfully sent,but I dont receive anything at all at my pachube account here https://pachube.com/feeds/55223 . If you have any alternative code,do you mind sharing.Because I keep looking on the internet , and no one write a good code based on GPRS module to pachube.com . I nearly giveup because not a lot of people know pachube.com . I might consider to offer $us10 for helping me ,with the code.I am no programmer,so I got dizzy when something like this happen. I study myself the AT command but I dont understand half of it. I do not know any expert.Help me please 
my circuit connection as below :
and LM35 is at analog input 0
