Sorry if this is obvious, I'm very new!
Say I have a simple solution simply keeps a record of my media collection. One of the fields is MediaType. I have a dropdown menu to a value list that contains names like "CD, DVD, Book, Xbox Game..." etc...
What I would like to do is depending of which option I choose for MediaType, a second container field, MediaTypeImage, then auto populates with an image of that type of media (so if I choose CD, an image of a CD appears.)
This seems simple enough, but I just can't figure it out! Any help much appreciated!
