    How to calculate total based on user selections?

    Asked by newmethodanceministries on October 12, 2015 at 03:17 PM

    I have multiple participant fields. Once the customer selects Yes to they would like to a T-shirt and the size (Plus sizes will be more), if each participant and T-shirt selection can be calculated into one total at the end

    For Example

    If a customer is registering 10 participants and each participant would like a T-shirt, 4 out of the 10 participants are plus size shirts.  (Workshop fee=$20 T-shirt Fee=$20/Plus Size $25.00)

    So that would be a total of $200 registration

    T-shirt Total $220.

    $420 would need to be calculated at the end. 

    Or for whatever they selected. How can I accomplish this?

    1. You can add a dropdown field with "How many participants do you want to register?"

    2. You can add calculation values to the fields, both the "How many participants" and for each t-shirt size:

    3. Now you can add a calculation widget and add all the fields to the calculation:

    You can test and clone the demo form:

    This should be possible with custom calculations. I would like to suggest checking the next guides:

    1) How to perform calculation in the form

    2) How to assign calculation value

    3) How to pass a calculation to a payment field

    Take a look at 'Calculated amount based on user selections and inputs' section of the next article to see it in action.

    I appreciate all of your help. I went through all of the tutorials. I am still having issues with the calculations. I have tried EVERYTHING lol. 

    When they choose a class and or if they choose a t-shirt size, it should be calculated. the calculations do not add up correctly. What am I doing wrong?

    Your calculations look good in general, but it seems that there are missing plus symbols between tshirtSize and participantClass fields. Please add them and re-check the form.

    Thank you.

    I have removed the last plus sign, and calculations seems to be fine now.

    Please test the form now.
