I've found some really useful guides on this site so i hope you can help me even further What am i doing? I have a exel based Product list saved as .txt i load this into javascript as follows:

function make2DArray (pfad){
 var Daten = loadFile(pfad);
 var Array = createArray(Daten);
 return Array;
}
function createArray(data_in){
 var Zeilen = data_in.split("\n");
 var Spalten = new Array();
for (var i=0; i<Zeilen.length; i++)
 {
 Spalten = Zeilen[i].split("\t");
 Zeilen[i] = Spalten.splice(0,Spalten.length);
}
return Zeilen;
};
function loadFile(file_in)
{
var file_out;
$.ajax({
 type: "GET",
 url: file_in,
 dataType: 'text',
 async: false,
 success: function(data){
 file_out = data;
 },
 error: function(){
 openDialog('Datei nicht gefunden', file_in + " konnte nicht gefunden werden.\n<br />Bitte wende dich an einen Troubleshooter oder Teamleader!");
 }
});
return file_out;
};

that's that you knew how my Array is made... anyway with this i have an Array[rows][cols] to work with now i have in array[rows][14] a price which i want to compare i load one line which is the existing produkt (1d Array) and my 2d array

function PackAusfiltern (arrzeile, arr) {
var Eingabearray = arr;
var Ausgabearray = "";
var BestandPreis = arrzeile[14];
BestandPreis = BestandPreis.replace(/,円/g, '.');
BestandPreis = parseFloat(BestandPreis);
//Here i get the Price of the existing Package which i want to compare

And now to my Actual Problem: I want to literate throug every Row, get the Value of column 14 and convert it to a number (some numbers are stored like "39,90" so i need to change the "," to ".")

i get here always an Error in line:

var zwischenspeicher = Eingabearray[i][14]+"";

it Says something like "for the property '14' is no value get able" (german IE 9...) Here is the for loop which should get the value, make it a number, compare it an delete elements where already the second line brings the error:

for (var i=0, j=Eingabearray.length; i<j; i++) {
 var zwischenspeicher = Eingabearray[i][14]+"";
 zwischenspeicher = zwischenspeicher.split(',').join('.');
 zwischenspeicher = parseFloat(zwischenspeicher);
 Eingabearray[i][14] = zwischenspeicher;
 if ((BestandPreis <= Eingabearray[i][14]) && Eingabearray[i][16] == 1)
 {
 var löschenPO = Eingabearray.indexOf(Eingabearray[i][17]); //find other pack code
 var löschenindex = Eingabearray.indexOf(löschenPO); // search other pack
 Eingabearray = Eingabearray.splice(löschenindex, 1); // delete other pack
 }
 };

just for information:

type(Eingabearray[i][14]); //= [object Number]
function type(obj){
alert(Object.prototype.toString.call(obj));
}

hopefully you get my bad English and the formatting works so you can tell me what stupid mistake i made^^ all the best and marry Christmas

I have an Excel -based product list saved as .txt. I load this into JavaScript as follows:

function make2DArray (pfad){

 var Spalten = new Array();

 error: function(){

return file_out;

That's so that you know how my Array is made...

Anyway, with this I have an Array[rows][cols] to work with. Now I have a price in array[rows][14] which I want to compare. I load one line which is the existing produkt (1D Array) and my 2D array:

And now to my actual problem: I want to literate through every row, get the value of column 14 and convert it to a number (some numbers are stored like "39,90", so I need to change the "," to ".").

I always get an error here in this line:

var zwischenspeicher = Eingabearray[i][14]+"";

It says something like "for the property '14' is no value get able" (German Internet Explorer 9...).

Here is the for loop which should get the value, make it a number, compare it an delete elements where the second line already brings the error:

What stupid mistake have I made?
