calculating the sum of three fields

PVMA 26 Nov, 2025

Hi Folks,

I'm trying to create a form in which the user will enter a number in three different fields, and then the sum of the three fields is shown in a fourth field. How to do this?

Thanks!

Hi PVMA

Using a JavaScript function, or PHP if the page will be submitted before the calculation is done.
