problem in coding

hello iwant to send data from two sensors one is lm35 and other heartrate through esp8266 i have a code which is giving error:exit status 1
a function-definition is not allowed here before ‘{’ token
please help
this is my code

#include<SoftwareSerial.h>
SoftwareSerial esp8266(2,3);
#define DEBUG true

void setup()
{
Serial.begin(9600); ///////For Serial monitor
esp8266.begin(115200); ///////ESP Baud rate
//pinMode(11,OUTPUT); /////used if connecting a LED to pin 11
//digitalWrite(11,LOW);

sendData(“AT+RST\r\n”,2000,DEBUG); // reset module
sendData(“AT+CWMODE=2\r\n”,1000,DEBUG); // configure as access point
sendData(“AT+CIFSR\r\n”,1000,DEBUG); // get ip address
sendData(“AT+CIPMUX=1\r\n”,1000,DEBUG); // configure for multiple connections
sendData(“AT+CIPSERVER=1,80\r\n”,1000,DEBUG); // turn on server on port 80
}

Here you are trying to define a function inside another function, but the dialect of C the Arduino uses doesn't allow that.
