Format Exception when trying to parseFloat(String)

I have a problem with my script. For some reason i get a Format Exception when i try to parseFloat() a String that i get from an InputField.

The Exception:

FormatException: Invalid format.

The Code:

"#pragma strict

import UnityEngine.UI;"

var input1 : String;
var input2 : String;
var input3 : String;
var input4 : String;

var inputF1 : InputField; //input Field 1
var inputF2 : InputField; //__""__ 2  
var inputF3 : InputField; //...
var inputF4 : InputField; //...
var result : Text;

 private final var R : float = 6371000; //Earth's radius in metre

var d : float; //distance to travel
var a1 : float; //latitude in dezimals
var b1 : float; //longitude in dezimals
var brng : float; //Angle you are going to

function Start () {


function Update () {


function ExitButton(){

function InputF1(){
	input1 = inputF1.text;

function InputF2(){
	input2 = inputF2.text;

function InputF3(){
	input3 = inputF3.text;

function InputF4(){
	input4 = inputF4.text;

function Calc(){
	//aFloat = parseFloat(input1);  I TRIED ALL THIS BEVORE WIHT ALL
	//bFloat = parseFloat(input2);	SIMPLE TEST. IT WORKED BACK THEN.
	//flaeche = aFloat * bFloat;
	//result.text = ""+surface;
	d = parseFloat(input3);
	a1 = parseFloat(input1);
	b1 = parseFloat(input2);
    brng = parseFloat(input4);
	var a2 = Mathf.Asin( Mathf.Sin(a1)*Mathf.Cos(d/R) +
                        Mathf.Cos(a1)*Mathf.Sin(d/R)*Mathf.Cos(brng) );
    var b2 = b1 + Mathf.Atan2(Mathf.Sin(brng)*Mathf.Sin(d/R)*Mathf.Cos(a1),
	result.text = a2+"°N "+b2+"°W "; 

I have no idea what this Exception is telling me. I am a more or less beginner programmer so please don´t be to harsh on me if the structure of the code is not that good.

The “result” variable is a Text variable which gets displayed in the UI.

Here a picture of the UI. (sry for it beeing German but i think that does not matter that much anyway.)

Thanks in Advance!

try float.Parse instead you can also use float.tryParse to handle invalid input

float converted = float.Parse(“17463274”);

Anyone? Could rly use a tip. Maybe i missed something? I have attached everything in the Inspector, so that´s not it.

EDIT WOW I am so stupid haha… I copied the Input Fields so they all still had the first input field function. Thanks for the help anyways, I guess. Took me a few hours to find that stupid mistake but i did find it after all.

Maybe this post helps someone in the future.
