How can I use calculation in my form?

Hello,

I have tried a few different widgets and such, but cannot find something that will allow me to have a read-only result based on a few field inputs. What I want to do is have three fields:

- How many people to be trained

- How many people per training session

- How many hours are needed per training session

I then want a read-only field that will calculate these three fields like this:

(#1/#2)*(7/#3)

Basically, we have a 7-hour workday. What I want to figure out is how many sessions we can squeeze into a 7-hour work days based on the length of each session. Then, how many days will it take to train all of the sessions.

Thanks,

Kevin

To make the calculation field readonly, please inject the following css in your form builder's CSS tab:

#input_11
{
  pointer-events: none;
}

Follow this link to know how to inject custom css in your form:

Here #input_11 is the id of my calculation control. In your case, this id will be different.

Please refer to this guide to know how to get your calculation field id:
