Using IF statements | WordPress.org

Hello @dankarr

Thank you very much for using our plugin. In Javascript, the equality operator is the double symbol ==. The single symbol = is used for assignment.

So, the equation would be:

(function(){
    if(fieldname3==85)
    {
       return (fieldname10-fieldname18)*600+(fieldname10-fieldname18)*fieldname33*0.115;
    }
    else
    {
        return filename18;
    }
})()

Note that you can use the IF operation in this case and make the equation simpler:

IF(fieldname3==85, (fieldname10-fieldname18)*600+(fieldname10-fieldname18)*fieldname33*0.115, filename18)

Best regards.
