You know that little gauge that has to fill up every time you attack? You know how it says "Attack" over it? I believe when you tell someone to use an item, that gauge will say "Potion" over it, until the item is used once the gauge fills up.

And I'm fairly certain that your character will then resume attacking automatically, although you may want to re-enter the "Attack" command, just in case.
The character will attack automatically but he/she won't attack after he/she kill the enemy he/she is attacking.

You can't use Items in Towns. Best find a save crystal.
