tracking device

Im installing my C program in Arduino but I'm getting this error, can someone please help me out.

missing termination " character

and the code is
sprintf(aux_str, "AT+HTTPPARA="URL","http://%s/demo_sim908.php?", url);

Did you mean

sprintf(aux_str, "AT+HTTPPARA=\"URL\",\"http://%s/demo_sim908.php?\"", url);

(please change the topic title)
