    Hi

    Hi 716paws,

    It only takes a minute to add an additional fee based on a condition like whether the dog is fixed or not. Let me show you how:

    1. In Form Builder, add a new checkbox or single choice field where users can indicate if the dog isn't fixed.
    2. Add a Product field for the $35 fee. Set its price to $35 and label it accordingly (e.g., "Unfixed Dog Fee").
    3. Use Conditional Logic to show or hide this $35 fee product based on the user's selection. For example, if the user marks that the dog isn't fixed, show the $35 fee product; otherwise, hide it.
    4. Ensure your payment integration (e.g., credit card payment field) includes this product so the total amount reflects the additional fee when applicable.

    If you want to add a percentage-based fee instead, you can also use the Tax feature in the Product List field to collect credit card processing fees as a percentage.

    Give it a try and let us know how it goes.

    Hi 716paws,

    I can see you're using the User-Defined Amount Payment Method to get the total from a Form Calculation widget. I understand you'd like to make an adjustment to the form by adding another fee that depends on another question field. But I noticed there's no additional field asking about the dog not being fixed.

    Can you share more details about how you'd like this to work? Are you still going to use a Dropdown element or another? Should the additional question be answered with Yes or No only? If yes, you can use another Dropdown element or a Single Choice element. Let me share a demo using a cloned form:

    1. In Form Builder, click on the Add Element menu on the left side.
    2. Under the Form Elements below the Basic tab, drag and drop a Dropdown element in whichever part of the form page you prefer.
    3. Now, select the Dropdown element and click on the Gear icon below it. In the Dropdown Properties on the right side, go to the Options tab.
    4. Under the box below the Options, add the options. Then, enable the Calculation Value and add the value of 35 for the option No.

    5. Next is to select the Form Calculation widget and click on the Wand icon below it.
    6. In the Form Calculation Widget on the right side, click on the Add Field button.
    7. Then select the additional Dropdown element, and add a plus sign between the fields.
    8. Finally, click on the Save button.

    Hi Kris

    Thank you for your assistance. To provide more clarification what I am looking to have happen is if a user selects no to the spayed or neutered question I need the $35 fee added to the total owed.


    Currently, I have the adoption fees and the $35 unfixed Dog fee listed as a product in my form. However, right now the conditional logic is not showing that product only if no is selected it is checking it all the time. How do I go about fixing this?

    Also, is there a way to set up an integration with Venmo or Zelle or other payment platforms in conjunction with the stripe connection? I was hoping to be able to set it up so that a user has to send their Venmo payment and they are given the total owed before they can submit the form.

    Hi 716paws,

    Unfortunately, you can't make a condition on the product list that will show the specific product only. It appears that you already added a separate Multiple choice field and Form calculation. Let me show you how to do it:

    1. In Form Builder, select your Spayed/Neutered? field and click on the Gear icon.
    2. Then, in the Multiple Choice properties, under the Options tab, turn on Calculation Values and set up the amount per option.

    3. While in Form Builder, select your Product list and click on the Credit card icon.
    4. Then, in the Payment Properties, set the Payment Type to User Defined Amount.
    5. Next, a pop-up modal screen will appear, click on the Yes, Change button.

    6. While in Form Builder, select your Adoption Fee amount and click on the Gear icon.
    7. Then, in Dropdown Properties, under the Options tab, turn on the Calculation Values and set the amount for each option.
    8. Next, under the Advanced tab, turn off the Hide field option.

    9. In Form Builder, select the Adoption Fee Total field and click on the Wand icon.
    10. Next, setup the calculations like you see below and click on the Save button.

    I was able to add the calculation values to the form but I also need a line item showing the extra $35 fee. Essentially I need to so that when the user gets their email confirmation is shows like a receipt the fee plus the adoption cost
