Hi.

It is possible with JotForm. You can do the statements with show/hide a form field condition.

Here is how to do this:

1) Click on Setup & Embed.

2) Click on Conditions.

3) Choose Show / Hide a form field and click on Next.

4) Make the arrangements as you see below.

Here is how it works:

Here is the sample form, feel free to clone it.

Thanks Beril, I cant get past "show/hide a form field" I get to the stage of selecting the line where it says: Do you have any children?

I then can see where the answer is "if yes" then show...but I have no idea how to instruct the program what to show?

From here I am lost

When you get to if "field" state "is filled"(or any other state you decide), you will see "Do" and "Field", simply you select what to "Do"(show or hide) and select which Field will obey that action. 

Example:

Hope this helps.
