I've already posted this but it was as a response deep within another thread so I thought that I would repost it here in case it is useful to someone who did not see the original.

Note that it uses my ControlEvents library to limit the range of inputs allowed to those applicable for each type - this is difficult to do normally. Also note that you can type into any of the text boxes and the appropriate values are displayed in all the others.

EDIT :- Fixed the need to disable unassigned variable check as pointed out by Erel.
