showing message when certain shipping option is selected.
 

i'm thinking there has to be a way for me to do this.

I want to add small Notices for customers to see when they select a certain type of shipping.

for instance if they choose UPS Next Day Air, I want Notice to appear that states that their order may not ship that same day, therefore may not arrive that next day.
things of that nature.
i have all these notices inserted into the checkout area already, but would like to modify it so only the ones that pertain to that exact shipping option show once that shipping option is selected.

i know theres got to be some "if" coding to make this idea work. :)
any help would be appreciated. thank you

anyone?

i dont know much but it might be something like

if shipping method "x" is selected. show next_day_air.tpl?

something like that? but written in code correctly?
