I want to have a form that has two text boxes side by side. Both text boxes will have an up arrow above them, and a down arrow below.
I want the user to have to use the up and down arrows to scroll through some single character - not type into the boxes manually.
On the first box, the user should be able to scroll up or down to pick letters A, E, I, O or U.
Depending on what letter is in box 1, depends on what values are available for box 2.
How would I achieve this?
