How to get text data from a Browser?

Hello,
I am building a Wifi application and try to get data from a browser. In this case I specifically try to have the user to set a low and high set point to control a water pump.

So far:
I am connected to the Wifi
if I click the buttons to set the output on or off, it works. (This is not really useful to me but I kept these lines there to see if my code works)

On the serial port I can read the command that are sent.

My issue is to get text from the input type=text lines. Whatever i do, I dont see any result being sent.
Are there any other ways to do it?

My Code: (Most of it borrowed from the net)

#include <Wire.h>
#include <UnoWiFiDevEd.h>
void setup() {
pinMode(13,OUTPUT);
Wifi.begin();
Wifi.println(“WebServer Server is up”);
Serial.begin(115200);
}
void loop() {
while(Wifi.available()){
process(Wifi);
}
delay(50);
}
void process(WifiData client) {
// read the command
String command = client.readStringUntil(’/’);
Serial.println(command);
// is “digital” command?
if (command == “webserver”) {
WebServer(client);
}
if (command == “digital”) {
digitalCommand(client);
}
}
void WebServer(WifiData client) {
client.println(“HTTP/1.1 200 OK”);
client.println(“Content-Type: text/html”);
client.println();
client.println("");
client.println(" “);
client.print(”");
client.print(“Click<input type=button onClick=“var w=window.open(’/arduino/digital/13/1’,’_parent’);w.close();“value=‘ON’>pin13 ON
“);
client.print(“Click<input type=button onClick=“var w=window.open(’/arduino/digital/13/1’,’_parent’);w.close();“value=‘OFF’>pin13 OFF
“);
//-----
client.println(””);
client.print(”<input type=text name=lowset
“);
client.print(”<input type=text name=highset
“);
client.println(””);
//-----
client.print(””);
client.println(””);
client.print(DELIMITER); // very important to end the communication !!!
}
void digitalCommand(WifiData client) {
int pin, value;
// Read pin number
pin = client.parseInt();
// If the next character is a ‘/’ it means we have an URL
// with a value like: “/digital/13/1”
if (client.read() == ‘/’) {
value = client.parseInt();
Serial.println(value);
digitalWrite(pin, value);
}
// Send feedback to client
client.println(“Status: 200 OK\n”);
client.print(F(“Pin D”));
client.print(pin);
client.print(F(" set to "));
client.print(value);
client.print(EOL); //char terminator
}

many thanks,
