Script Help - Message on Item Use

[Plarux]

Hello,

 

I'm trying to add a message that is displayed when the player uses an item, such as a chem. One that the player has to click "Ok" or enter on to get it to disappear. Could someone possibly show me a script that would do such a thing? I know how to create messages and understand how the buttons work, but have no idea how to use papyrus.

 

Thank You,
