data logging after rf433mhz transmittion

// Define output strings
String str_humid;
String str_temp;
String str_freq;
String str_out;
// Create Amplitude Shift Keying Object
RH_ASK rf_driver;

void setup()
{ // Initialize ASK Object
  rf_driver.init();
  // Setup Serial Monitor
  Serial.begin(9600); 
 
}

void loop()
{ // Set buffer to size of expected message  (note: see Ask_receiverTest to make this variable.
  //uint8_t buf[RH_ASK_MAX_MESSAGE_LEN];
  uint8_t buf[17];
    uint8_t buflen = sizeof(buf);
  // Check if received packet is correct size
  if (rf_driver.recv(buf, &buflen))
  { // Message received with valid checksum
    // Get values from string
    // Convert received data into string
    str_out = String((char*)buf);
    
    // The entire message is in the String str_out
    // Split string into three values

    // First, find the offsets of the two commas
    int comma1 = str_out.indexOf(",");
    int comma2 = str_out.indexOf(",", comma1+1);

    // Then extract the substrings
    str_humid = str_out.substring(0, comma1);         // before first comma
    str_temp = str_out.substring(comma1+1, comma2);  // between the two commas
    str_freq = str_out.substring(comma2+1);          // after the second comma

    
    // Print values to Serial Monitor
    Serial.print("Humidity: ");
    Serial.print(str_humid);
    Serial.print("  - Temp: ");
    Serial.print(str_temp);
     Serial.print(" - Frequency: ");
     Serial.println(str_freq);

  }  }
I want to log the data on the data logging shield V1.0, Ive tried to combine the both codes but I'm not getting any transmittion from the receiving arduino when I add the data logging elements to it
here is the code that Ive combined with my receiver code:
// Include RadioHead Amplitude Shift Keying Library
#include <RH_ASK.h>
#include <SPI.h>
#include <SD.h>

const int chipSelect = 10;

// Define output strings
String str_humid;
String str_temp;
String str_freq;
String str_out;
// Create Amplitude Shift Keying Object
RH_ASK rf_driver;

void setup()
{ {// Initialize ASK Object
  rf_driver.init();
  // Setup Serial Monitor
  Serial.begin(9600); }
 

  Serial.print("Initializing SD card...");

  // see if the card is present and can be initialized:
  if (!SD.begin(chipSelect)) {
    Serial.println("Card failed, or not present");
    // don't do anything more:
    while (1);
  }
  Serial.println("card initialized.");
}

void loop()
{ // Set buffer to size of expected message  (note: see Ask_receiverTest to make this variable.
  //uint8_t buf[RH_ASK_MAX_MESSAGE_LEN];
  uint8_t buf[17];
    uint8_t buflen = sizeof(buf);
  // Check if received packet is correct size
  if (rf_driver.recv(buf, &buflen))
  { // Message received with valid checksum
    // Get values from string
    // Convert received data into string
    str_out = String((char*)buf);
    
    // The entire message is in the String str_out
    // Split string into three values

    // First, find the offsets of the two commas
    int comma1 = str_out.indexOf(",");
    int comma2 = str_out.indexOf(",", comma1+1);

    // Then extract the substrings
    str_humid = str_out.substring(0, comma1);         // before first comma
    str_temp = str_out.substring(comma1+1, comma2);  // between the two commas
    str_freq = str_out.substring(comma2+1);          // after the second comma

    
    // Print values to Serial Monitor
    Serial.print("Humidity: ");
    Serial.print(str_humid);
    Serial.print("  - Temp: ");
    Serial.print(str_temp);
     Serial.print(" - Frequency: ");
     Serial.println(str_freq);

  }
  
  File dataFile = SD.open("datalog.txt", FILE_WRITE);

  // if the file is available, write to it:
  if (dataFile) {
    dataFile.println(str_humid);
    dataFile.println(str_temp);
    dataFile.println(str_freq); 
    dataFile.println(str_out);   
    dataFile.close();
    // print to the serial port too:
    Serial.println(str_humid);
    Serial.println(str_temp);
    Serial.println(str_freq);
  }
  // if the file isn't open, pop up an error:
  else {
    Serial.println("error opening datalog.txt");
  }}
I know that my coding isnt up to standard, so I need a little help in the right direction
Thank you
