Hi Marco,

Thanks for reaching out to Jotform Support. With Jotform, you can create your forms, and apply calculations and validations on them. Let me show you how to perform calculations with your form:

• In Form Builder, click on the Add Element button on the left
• Under the Widgets tab, click on the Form Calculation widget.
• In the Form Calculation Widget, use the Add Field button and mathematical operators to perform your calculation:
  

Now, we can use a Paragraph field and conditions to perform validations. Let me show you an example below:

• On the Form Elements menu, I used the Paragraph element to create my error message.
  
• Now, click on Settings and Conditions.
• Create a new Show/Hide field condition similar below:
  

Here's how my demo form will work:

That's it. We also have a guide on How to Perform Calculations Using a Widget that you can check out.

Give it a try and let us know if you need any help.
