    My staff is going to access a form on our site which will help expedite our quote process.
    I would like them to be able to calculate gratuity and tax if possible. I understand that this isnt implemented in the current version however I was wondering if there is any available 'code'. The site is http://www.whirlyballatlanta.com and the form is at

    Hi DJ,

    I don't know of any available code that does quite what you're looking to do. A couple pointers if you feel like taking a stab yourself.

    • 1 - Assuming you want to show these calculations on the form itself, you'll want to use Javascript to calculate these numbers based on the value of the Total field.
    • 2 - You can bind a jQuery function to the change event of the Total field so any time the total changes, you can update your gratuity and tax fields.

    David,
    How exactly would you bind a jquery function to the change of the total field? I'm struggling to get a similar thing to work.

    Thanks in advance

    These two links will probably help:

    Bind - jQuery API

    Change - jQuery API

    I'm not having any joy with this, is this correct as I can't gget it to do anything

    jQuery('.ginput_total').bind('change',function(){
    alert('the total has changed');
    });

    Hi Tom,

    We've added a customizable javascript function to handle making changes to the total. Here is a related walk through that should get you started:
