HF RFID WITH GPRS MODULE AT COMMANDS USING ARDUINO

HI
I’m working on gprs module with hf rfid using arduino uno.i m getting trouble in gprs AT command,where i have established my tcp connection using arduino code,but i got error in at+cipsend

my arduino code are here

plz help anyone…plz
thanks in advance

Hi,
I was trying the new GPRS module(sim900a) and its works but i having an error when i want to post it in xampp server.
