    Hi Ally,

    I have a field called: Writing and another called: Estimate Overall, i need to do something like:

    If Writing is 6.5 or Less then do Writing = overall score – 0.5

    and if writing is greater than 6.5 then do: writing = overall score – 0.75

    Writing is a checkbox field. and estimate overall is just a text based.

    Hope this makes sense 🙂

    Thanks Aaron

    Thanks Ally,

    I think i understand :).

    This is my full JS code so you can see what we are doing 🙂

    // Start Yes
    
    jQuery(function ($) {
        var calculate = function () {
            var total = 0;
    
            var listening = $('.quform-field-1_18:checked').val();
            if (listening && $.isNumeric(listening)) {
                total += parseFloat(listening);
            }
    
            var reading = $('.quform-field-1_19:checked').val();

            var writing = $('.quform-field-1_20:checked').val();

    Hi Ally,

    Forgot to say the writing field is not a checkbox my mistake so would i just change the top var writing to be:

    var writing = $(‘.quform-field-6_84).val();

    Thanks
    Aaron

    Hi Ally,

    So this is what i need to do 🙂

    i have 2 checkboxes :).

    Listening and Reading so the first calculation is this we need to get the score for “Writing” which is not present except but will be a hidden field.
    So the calculation i need to do is: if overall band score is <= 6.5 do -0.5 if its > 6.5 -0.75
    Now for the second calculation i need to do:
    Listening + Reading, the listening = speaking.
    then: Listening + Reading + Writing + Speaking
    Overall Band Score = Listening + Reading + Writing + Speaking / 4

    I going to try and work on it, but would be good to have some pointers 🙂 as i am new to javascript so learning as i go.

    Also i appreciate all your help.

    Thanks
    Aaron
