problem for program for send data to web server

Dear All .
I Have Problem in Program
I Create program for send data to web server , but when make verify for program give me some error, please help me .

#include <ESP8266WiFi.h>
const char*ssid="ssidename";
const char *password="ssidepassword";
int ledPin=D5;
String request;
// int index;
WiFiServer Server(80);
IPAddress ip(192,168,1,99);
IPAddress gateway(192,168,1,1);

void setup() {
Serial.begin(115200);
delay(10);
pinMode(ledPin,OUTPUT);
digitalWrite(ledPin,LOW);
Serial.println(F("setting static ip to:"));
Serial.println(ip);
Serial.println();
Serial.println();
Serial.println("connecting to");
Serial.println(ssid);
IPAddress subnet(255,255,255,0);
WiFi.config(ip,gateway,subnet);
WiFi.begin(ssid,password);
while
( WiFi.status()!= WL_CONNECTED)
{delay(500);
Serial.print(".");}
Serial.println("");
Serial.println("WiFi connected");
Server.begin();
Serial.println("Server started");
Serial.println("use this URL:");
Serial.println("http://");
Serial.println("WiFi.Localip()");
Serial.println("/");}

void loop() {
Server.available();
if ("!client"){"return";}
Serial.println("new Client");
while
('!Client.available()');
{delay(1);};
Client.read Stringuntil("\r");
Serial.println("request");
// client.flush();
int value=LOW;
if(request.index of("/LED=ON")!=-1)
{digitalWrite(ledPin,HIGH);
value=HIGH;}
if(requestindex0f("/LED=OFF")!=-1)
{digitalWrite(ledPin,LOW);
value=LOW;}
client.println("HTTP/1.1 200 OK");
client.println("content-Type:text/html");
client.println("");
client.println("<!DOCTYPEHTML>");
client.println(" ");
client.println("Led Pin is now");
{if (value==HIGH)
{client.print("on");};
else {'Client.print("off")';}}
client.println("

");
client.println("Click <a href="/LED=ON">heretrun the LED on pin 5 ON
");
client.println("Click <a href="/LED=OFF">heretrun the LED on pin 5 OFF
");
client.println("");
delay(1);
Serial.println("Client disconnected");
Serial.println("");

Help us to help you.

What are the errors ?

It would also help if you put your code in code tags when posting it here.

 if ("!client"){"return";}

?

Is that the whole error message ?

Stop putting the { on the same line as the function/statement.
Stop putting ANYTHING after the {.

Put every { on a line BY ITSELF.
Put every } on a line BY ITSELF.

Use Tools + Auto Format to fix your piss-poor indenting.

Of course, you won't be able to because your curly braces are all screwed up.

Use Tools + Auto Format to fix your piss-poor indenting.

Of course, you won't be able to because your curly braces are all screwed up.

You can tweak the settings for Auto Format to move each curly brace on its own line if you want to, and other tricks too, such as removing blank lines in functions.
Before

void setup(){
  Serial.begin(115200);
  Serial.println("Hello");
  
  Serial.println("After a blank line in the code");}

void loop()
{Serial.println("In loop");}

After Auto Format

void setup()
{
  Serial.begin(115200);
  Serial.println("Hello");
  Serial.println("After a blank line in the code");
}

void loop()
{
  Serial.println("In loop");
}

I did not know that. Can you describe how?

This is using Windows. Other OS's may be different.

In the IDE File/Preferences and click on the link to preferences.txt, although it is not obviously a link. In the folder that opens you will find a file named formatter.conf Open it with your favourite editor.

FWIW here is my version of formatter.conf which I have modified to suit me after some exerimentation

# This configuration file contains a selection of the available options provided by the formatting tool "Artistic Style"
# http://astyle.sourceforge.net/astyle.html
#
# If you wish to change them, don't edit this file.
# Instead, copy it in the same folder of file "preferences.txt" and modify the copy. This way, you won't lose your custom formatter settings when upgrading the IDE
# If you don't know where file preferences.txt is stored, open the IDE, File -> Preferences and you'll find a link
