    Thank you for contacting us.

    I have updated your form a bit, a Total calculation field has been added and payment field is configured to use it.

    Please re-check the form.

    Thanks - will this show up as GST on the invoice for the customer ?
    And how can we make the GST included and total payable section look more professional ? Like closer together and show the decimal places for the dollar value

    GST INCLUDED text field that is right above My products field will not be shown inside of the Autoresponder email that is sent to your users because it is a text field. You can customize email template and include it inside of the email. 

    How to Edit the Email Template for Notifications and Autoresponders

    GST Included calculation field will be shown inside of the Autoresponder email. 

    Regarding positioning of the fields - Add this CSS code to your form:

    li#id_45 {

        padding-bottom: 0;

        margin-bottom: 0;


    li#id_47 {

        padding-top: 0;


    How to Inject Custom CSS Codes

    If you want to show empty decimals, you have to check Show Empty Decimal Places inside of the setting of your Form Calculation fields (GST Included $ and Total). 


    I would also suggest you to increase the width of the My products input field, by adding this CSS code:

    input#input_47_donation {

        width: 80px!important;
