I'm trying to change the color of text lines containing "Accepted" to green and all others to red but when i upload my file all the lines are green. What am I doing wrong? I really don't know why the else statement is not read.
document.getElementById("openFile").addEventListener("change", function(){
var file = this.files[0];
var fr = new FileReader();
fr.onload = function(){
document.getElementById("fileContents").textContent = this.result;
let lines = document.getElementById("fileContents").textContent.split('\n');
let parser ='';
for(let line = 0; line < lines.length; line++){
if (lines[line].substring(0,3)==="ACK"){
parser += lines[line].substring(0,3) + "\t" + lines[line].substring(49,108).trim() + "\t" + lines[line].substring(109,115) + "\t" + lines[line].substring(149,159).replace(/as/gi,"\tAccepted").replace(/rj/gi,"\tRejected") + '\n';
}
else if (lines[line].substring(0,3)==="MSG"){
parser += lines[line].substring(0,3) + "\t" + lines[line].substring(35,159).replace(/,/,"").trim() + '\n';
}
}
document.getElementById("fileContents").textContent = parser;
if (parser.includes("Accepted")){
document.getElementById("fileContents").style.color = "#00FF00";
}
else {
document.getElementById("fileContents").style.color = "#FF0000";
}
}
fr.readAsText(file);
},false)

let parser = '';
let para;
for(let line = 0; line < lines.length; line++){
para = document.createElement("p")
para.innerHTML = lines[line];
if (lines[line].substring(0,3)==="ACK"){
let sub1 = lines[line].substring(0,3) + '\t';
let sub2 = lines[line].substring(49,108) + '\t';
