I cannot get how the "Flag" works. This in an example that I have foun on internet. I cannot get how the object where you can see the flag for each nation works.
It works in the most basic way (It is in Version 7); for each country in the list there is a Text Object with the relevant flag as the image - hard coded if you will, each object has a Conditional Show (Layout Tab) to only show when Country = 'Netherlands' for example.
So if we have 32 countries we have 32 Text Object images and as 'Country' is set to Always One Value Selected only one image is displayed at once.
A much more efficient way to achieve the effect would be to use a Bundle Info Load to assign the flag images to each country and then use a single Text Object with a info(Country) function.
