How can I select a name from a dropdown list and fill in another field

Hello,

I love your product and use it a lot. Thank you for keeping it so simple and powerful.

Question: I very often have the need to work with 10-20-or even 50 people at a time. I always use a Jotform to evaluate their presentations and your product is perfect for this.

How can I use a file that has the company name and email address in a dropdown list so that when I choose the company name from the list, Jotform automagically fills in the email address associated with that company?

I need to do this very often and for many companies at a time. I would prefer to NOT hard code this if possible.

What do you suggest?

Thank you for using JotForm and for your kind remarks. We greatly appreciate it. :)

There are 3 ways to achieve that but here's the easiest one to start with.

1. Add a dropdown field to your form.

2. In the dropdown settings, add your companies into options.

Then under it, enable the calculation value and assign the email address on each of the company.

You can leave the empty option blank.
You can also paste the values in the calculation value if you want to.

3. Add Form Calculation widget to your form and label it email address. 

Then in the calculation wizard, add the company field and switch states to A-Z. This will capture the value into string format. See screenshot below:
