How to populate email field with a value from another field ?

Our email format is first initial plus last name @ourdomain.org (so Jane Doe would be jdoe@ourdomain.org).  Is there a way I can make the form fill in the email address after the user fills in their first and last name?

Hello,

Of course, you can auto-populate an email field, you can refer to this guide : 

http://www.jotform.com/help/286-How-to-Populate-Field-with-a-Value-from-another-Field

You should add the first and last name fields : 

And an email field.

You should add a condition, it should look like this :

Here is my sample form, you can clone it if you want :

Thank you, that's a start.  But our emails are the first initial only, not the whole first name, then last name @ourdomain.org.  Is there a way to get it to just pull the first letter of the first name?

I really apologise for confusion.

Here is the correct way to do that.

First, add the Substring Widget, do it as the image below :

Now, you should add this CSS code, this will hide the field, do it as the image below : 

#id_6{display:none;}

This is the result : 

You can see my result here :

Cheers !

Am I supposed to paste #id_6{display:none;} at the top of the existing CSS or replace it?  If I paste it above it doesn't hide it and if I replace the existing CSS it removes all other formatting.

Also, when I tested it, I got "0@ourdomain.org".

Hello,

Sorry , the correct code for your form is this , you can paste it at the top of the existing CSS code: 

#id_75{display:none;}

You are getting a "0" into your email feld because this is taking the values as numbers, please change it as the image below : 

Your condition should look like this : 

I hope that helps.

Please, let us know if you need more help, we will be glad to help you.

Of course!  Sorry - I should have noticed that it was reading it as numeric values!  That's what happens when you're doing too many things at once!  And it's now hiding that first initial field as well. 

Thanks so much!!!

One more question - If I need to un-hide that hidden field, how do I find it?

You're welcome.

We are here to help you , if you want to un-hide the field, simply remove the code provided, if you do it the field will be shown in  the form.

If you need further assistance, don't hesitate to contact us.

Regards.

I couldn't find the field in order to remove the code, so I added a new substring and adjusted the formula for the email field, but now the new substring won't hide when I enter that CSS code telling it to hide.

This is possible to inspect elements in Google Chrome to get the corresponding field IDs.

Alternatively, you can select fields and add CSS using Form Designer.

Thank you.

I tried this and it still isn't hiding.  I give up!

Hi,

I've checked your form and I can see there is any CSS code :

Follow the setps as explained above by my collegue, go to Designer and paste the CSS code.

#id_75{display:none;}
