Rea Time Calculation using Javascript

This JS should do it for you. However, it is based on the screenshot, any change you make to it, may cause it to break:
Qualtrics.SurveyEngine.addOnReady(function () {
    let quest = this,
        qc = quest.questionContainer,
        all_inputs = qc.querySelectorAll("select");


    all_inputs.forEach((item) => {
        item.onchange = function (e) {
            let row = e.target.parentElement.parentElement,
                value = parseInt(e.target.value),
                text_boxes = row.querySelectorAll(".InputText");
            if (value > 1) text_boxes[1].value = "100%";
            else if (value === 1) text_boxes[1].value = "50%";
            else text_boxes[1].value = "";
        };
    });
});

Here's a demo.

https://community.qualtrics.com/XMcommunity/discussion/comment/41382#Comment_41382So below is the code that I am trying to implement.
Qualtrics.SurveyEngine.addOnReady(function()
{
document.getElementById('QR~QID1#1~1').onchange = function(){

var obj1 = document.getElementById('QR~QID1#1~1').value;

if(obj1 == "0: Not Met"){
document.getElementById('QR~QID1#3~1~1~TEXT').value = "0%";
}

if(obj1 == "1: Patrially Met"){
document.getElementById('QR~QID1#3~1~1~TEXT').value = "75%";
}

if(obj1 == "2: Met"){
document.getElementById('QR~QID1#3~1~1~TEXT').value = "100%";
}

if(obj1 == "3: Exceeds"){
document.getElementById('QR~QID1#3~1~1~TEXT').value = "130%";
}

}

});
It doesn't seem to be working. Any ideas?

Most probably your refrences are off.
