ARDUINO WIFI SHIELD CODE

hello guys. i did this code to control the led on pin 6 through ip.
bet the LED always on and when i click turn on or turn off on web browser nothing happen.
what is my error plz?

#include <SPI.h>
#include <WiFi.h>

IPAddress ip(192, 168, 0, 120);
char ssid = “TP-LINK_7035CE”; // your network SSID (name)
char pass = “(sabra*123)”; // your network password

WiFiServer server(80); // create a server at port 80

String readString; // stores the HTTP request

void setup()
{
WiFi.config(ip);
pinMode(6, OUTPUT); //pin selected to control LED
//start WIFI
WiFi.begin(ssid, pass); // initialize WiFi device
digitalWrite(6, LOW);
server.begin();
}

void loop(){
// Create a client connection
WiFiClient client = server.available(); // try to get client
if (client) {
while (client.connected()) {
if (client.available()) {
char c = client.read();

//read char by char HTTP request
if (readString.length() < 100) {

//store characters to string
readString += c;
//Serial.print(c);
}
//if HTTP request has ended
if (c == ‘\n’) {

///////////////
client.println(“HTTP/1.1 200 OK”); //send new page
client.println(“Content-Type: text/html”);
client.println();
client.println("");
client.println("");
client.println(“Home Automation”);
client.println("");
client.println("");
client.println(“

Home Automation

”);
client.println("
");
client.println("
");

client.println("<a href="/?lighton"">Turn On Light");
client.println("<a href="/?lightoff"">Turn Off Light
");

client.println("");
client.println("");

delay(1);
//stopping client
client.stop();

//// control arduino pin
if(readString.indexOf("?lighton") >0)//checks for on
{
digitalWrite(6, HIGH); // set pin 6 high
}
else{
if(readString.indexOf("?lightoff") >0)//checks for off
{
digitalWrite(6, LOW); // set pin 6 low
}
}
readString=""; //clearing string for next read

}
}
}
}
}

what is my error plz?

You misspelled please. You failed to include ANY Serial.print() statements to see what is actually happening. You failed to use any tabs to make your code readable.

Other than that, who knows?
