    Hello, and congratulations on this very good plugin.
    Can someone help a bit and and point out how I can perform various operations (mostly arithmetic) on the inputted data?

    In the FAQ, it is mentioned to use fm_get_form_item(itemID) via javascript, but I cannot access any data from the database.
    For example :

    <script type=”text/javascript”>
    <!–
    function js_bmi(){
    var js_varos,js_ypsos;
    js_varos=fm_get_form_item(varos);
    js_ypsos=fm_get_form_item(ypsos);
    return js_varos/((js_ypsos/100)*(js_ypsos/100));
    }
    window.onLoad=document.write(js_bmi());
    //–></script>

    If I manually replace the fm_get_form_item(…) functions with their current database values, the output is correct, but I want to access the data that each user puts there.

    This specific part is a BMI calculator, the user inputs his weight and height through a form and I want the function needs to access the form data and calculate the BMI.

    Any help would be much appreciated!!!!!!
