I am encountering issues with the text box summing as it is providing me with

Hey everyone, I hope you're all having a good morning. I'm facing an issue with 4 text boxes that should be summed up and the total displayed in 1 text box. However, instead of getting the correct total value, I seem to be getting something else which is not right. I suspect it might be due to parsing errors. Any assistance on this matter would be highly appreciated. Below you can find my code along with a screenshot showing the incorrect total result: Check out this picture for reference

Thank you in advance,

    <script type="text/javascript">
function myFunction() 
{

    var v1 = form1.txtCu2Row.value;
    var v2 = form1.txtCu3Row.value;

    var v3 = v1 + v2

    var v4 = form1.txtCu4Row.value;
    var v5 = form1.txtCu5Row.value;

    var v6 = v4 + v5



    form1.txtTotalCuAB.value = parseInt(v3) + parseInt(v5);


}

Using the parseInt function is crucial when retrieving a value, such as from an input field, because the returned data is in string format. Without converting it into an integer using parseInt, mathematical operations cannot be performed on the variable.

Once the value is parsed, it becomes an integer and can then be utilized for calculations, ensuring that the code functions correctly.

Implement this method to achieve the desired outcome.

function myFunction() 
{

    var val1 = parseInt(form1.txtCu2Row.value);
    var val2 = parseInt(form1.txtCu3Row.value);

    var total1 = val1 + val2;

    var val3 = parseInt(form1.txtCu4Row.value);
    var val4 = parseInt(form1.txtCu5Row.value);

    var total2 = val3 + val4;

    form1.txtTotalCuAB.value = total1 + total2;

}

If you want a more concise version eliminating unnecessary variables, consider this approach.

function myFunction() 
{

    var val2 = parseInt(form1.txtCu2Row.value);
    var val3 = parseInt(form1.txtCu3Row.value);

    var val4 = parseInt(form1.txtCu4Row.value);
    var val5 = parseInt(form1.txtCu5Row.value);

    form1.txtTotalCuAB.value = val2 + val3 + val4 + val5;

}
