    Je veux lier les options au prix total du service. Je suis venu essayer Jotform pour voir un petit peu et simplifier nos ventes. Le prix exacte s'affiche dans le widget calculator mais ce n'est pas ce que le client paiera. Existe-t-il un moyen ?

    Hi sxqo3dx,

    Thanks for reaching out to Jotform Support. Our French Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in French, let us know and we can have them do that. But, it might take a while until they're available again.

    Now, coming back to your question, since the total should also include the selection options from the Multiple Choice field, we need to use the User Defined Amount option in the connected payment gateway. To do that, we should also use a basic element for Lite. You can use a Single Choice element for the option Lite, and a Dropdown element for the quantity. Let me walk you through it:

    1. In Form Builder, click on Add Element in the upper-left corner of the page.

    2. Under the Basic tab, select Single Choice, then add the field label and the option

    3. Click on the field's Gear icon on the right, and go to the Advanced tab on the Properties panel.

    4. Toggle Shrink to On.

    5. Click on Add Element again, and select Dropdown from the Basic tab.

    6. Add the label, and the options as needed.

    7. On each field's Properties panel under the General tab, toggle Required to On.

    8. Click on the Form Calculation widget you have on your form, and select the Wand icon.

    9. On the Widget Settings panel, set the calculation as shown in the screenshot below, and click on Save at the bottom.

    10. Click on the Payment Properties icon on the right side of the page.

    11. From the Payment Type dropdown, select User Defined Amount.

    12. Scroll down a bit to see the Get Price From dropdown, and select the Form Calculation widget.

    13. Click on Save at the bottom.

    Merci beaucoup !

    Je commence à comprendre les mécaniques de jotform.

    Cependant nous vendons un service donc il y a un prix minimale. Et c'est aussi problématique que les clients puissent modifier le prix final. J'aimerais savoir si c'est possible ou non sur ce site.


    Merci !

    Hi sxqo3dx,

    If the suggested workaround doesn't work for you, you can also consider keeping the My Products field, and add the options as part of the product list. Check out the screencast below for your reference.

    To answer your question on whether form fillers can change the price on the suggest workaround above, the answer is no, they can't.

    Let us know if you have any other questions.
