Tony,
You can update/unhide a list box with the valid selection as determined by
the user's selection of option button.
There's no points showing the user 50 kinds of truck if they selected cars.

Hello,
I used these button.
My problem is that I want it in Two-Levels.
For Example:
I have to choose what kind of vehicle:
Cars, Motors, Trucks...

And if I choose cars I want to see: BMW, Opel, Mazda...
but If choose trucks, I wan to see it's relative options...
Then, when I choose it, I want a specefic visual basic code to be run.
(IF I choose Cars, then Mazda, I want to run a sub called
"Import_mazda()")
