Filling InfoTable with values doesn´t work

Hello! I am currently working on Project in Thingworx: My Goal is to visualize data I get from a csv file in two line Charts.

For that, I created a Mashup with a big TextBox, in which i copypaste the csv data in runtime. In addition, i have an grid widget and two linechart widgets.

First of all, after pasting the csv data into the TextBox, a Service is called which parses the data and fills the infotable. The Service's Output is a infotable and the Input Parameter is a string. By now, it Looks like the infotable is filled with empty values so i am kind of confused right now...

My service looks like this:

var txt = CSVinput;
var i = 0;

//var valArray = txt.replace("\n"," ");
var valArray = txt.split(" ");

var params = {
infoTableName : "InfoTable", 
dataShapeName : "LogDataShape"
};
var result = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params);

var cnt = 0;
while (i < valArray.length-1){
    var row = new Object();
    if(cnt == 0){
  row.DateTime = valArray + " " + valArray[i+1];
        cnt = 1;
    }
else if(cnt == 1){
        row.Temperature = valArray;
        cnt = 2;
    }
    else if(cnt == 2){
        row.Press_601_mbar = valArray;
        cnt = 3;
    }
    else if(cnt == 3){
        row.Press_651_mbar = valArray;
        cnt = 0;
        result.AddRow(row);
    }
i++;
}

the Input string looks like this: in the TextBox, there is exactly one space between each value and I asume a "\n"-endline at the end of the last value.

I would really really appreciate any kind of advice or help you can give me!!

Thank you so much in advance!
