Calculer au sein d'un formulaire

Je suis en train de créer un formulaire et j'aimerai faire une case comme dans l'image ci dessous.

Selon la valeur que je met le tarif de l'assurance affichée change . Plus la valeur auglebte plus le tarfi augmente.

Hi eatgestiondescomptes,

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, I understand the issue, but can you share with us the Form URL so we can take a look into it? Let me show you how:

1. In Form Builder, click on Publish on the orange navigation bar.
2. Under the Quick Share Tab, hover your mouse over to the Direct Link of Your Form section.
3. Then, click on the Copy Link button.

Once we hear back from you, we'll be able to move forward with the solution.

Je Souhaite connecter les 2 champs de texte.
Lorsque le premier est rempli ( avec une valeur ) le deuxième donne en fonction de la valeur un tarif.
je n’ai pas encore créé de formulaire

bien à vous

you did not understand.

I want to connect the 2 text fields.

When the first is filled (with a value) the second gives a rate based on the value.

I haven't created a form yet

Yours sincerely
