I have a more complex form currently built, but for the purpose of this support query I have created a much smaller example to see if it will work.
On a form (http://www.moygac.com/testform) I have got 3 different drop-down fields, currently set as football teams. What I essentially want to do is populate the options for a fourth drop-down field with whatever selections have been made in the first 3.
For example, if I select as follows: Team1 Liverpool, Team2 Leeds, Team3 Barcelona
I would like the options for the fourth drop-down (Final) to only be Liverpool, Leeds or Barcelona.
I'm sorry if this comes across as a very simple question but I have been through the documentation and the previous support requests and I cannot see an example which explains it to me.
