I'm creating a list of pre-definded codes for a drop down list e.g. 1, 2, 3
However I'd like to indicate to the user with the aid of a pop up or note saying what 1, 2 or 3 actually means to ensure they enter the right value.
Instead of simply entering 1, 2 or 3 I could put a word description in but I'd further like to analyse the data and create graphs which necessitates using numbers only.
Is this possible or does any have a better suggestion
thanks
