Enhancing functionality through the press of a button

I wrote a script that, upon button click, finds the closest location to your current position by searching through an array. It then locates the corresponding entry in another array and adds a number to that entry. However, I encountered a problem with appending the value. Instead of starting with "0" and adding 1 to make it "1", it displays as "01". I initially thought this was due to it being treated as a string, so I attempted parsing it as an integer which didn't resolve the issue. It seems like there might be an issue with how I set the values in the array initially. I looped through the first 200 values and set them to 0, but I want this operation to run only once. Then, each time the button is clicked, it should append the inputted number to a text field. I'm uncertain about the next steps to take to address this concern. Here's the code section:

I've tried to pinpoint the critical sections of my code where I suspect the problem exists.

Here's a screenshot showing the issue (the entered value gets attached at the end instead of getting added):

jQuery(function($){



    var Loc1;
    var Loc2;
    var service;
    var marker = [];
    var pos;
    var infowindow;
    var placeLoc
    **var j;**
    **var markerValue  =  [];**

            **for (j = 0; j<200; j++ ){

        markerValue[j] = 0;


    }**

    var markers;

    var x = 0, y = 0,
        vx = 0, vy = 0,
        ax = 0, ay = 0;

    var points;


    var sphere = document.getElementById("sphere");
    var counting = false;
    var counter = 0;
    var numberOne;

if (window.DeviceMotionEvent != undefined) {
    window.ondevicemotion = function(e) {

        ax = event.accelerationIncludingGravity.x * 5;
        ay = event.accelerationIncludingGravity.y * 5;

        document.getElementById("counterSpan").innerHTML = Math.round(counter*10)/10;
        //document.getElementById("accelerationX").innerHTML = Math.round(e.accelerationIncludingGravity.x * 10)/10;
        //document.getElementById("accelerationY").innerHTML = Math.round(e.accelerationIncludingGravity.y * 10)/10;
        //document.getElementById("accelerationZ").innerHTML = Math.round(e.accelerationIncludingGravity.z * 10)/10;

        var moveX = Math.round(e.accelerationIncludingGravity.x * 10)/10;
        //var moveY = Math.round(e.accelerationIncludingGravity.y * 10)/10;
        //var moveZ = Math.round(e.accelerationIncludingGravity.z * 10)/10;

        if(moveX > 5 || moveX < -5) {
            counting = true;
            //alert(counting);
            if(counter < 100){counter+=0.01;}
            }

After reviewing the code, it appears that you are fetching the value here:

numberOne = $("#numberOne").val();

This should be updated to:

numberOne = parseInt($("#numberOne").val());

You are using parseInt in the minmax() function, but this function is not being utilized. If this was intended to parse the value as an integer, there is a flaw as it only returns a parsed value between 0 and 100:

function minmax(value, min, max) 
{
    // Swap these two conditions, FIRST CHECK FOR isNaN.
    if(parseInt(value) < 0 || isNaN(value)) 
        return 0; 
    else if(parseInt(value) > 100) 
        return 100; 
    else return value; // Here you return the original value, not the parsed integer
}
