inventory slot organizer trigger request

[ShadowBladeX]

i want an trigger that organizes an inventory slots just like an rpg (ex: slot 1 right hand weapon, slot 2 left hand sub-weapon/shield slot 3 head gear) so if an item is placed on the wrong slot it will say "You placed your weapon/armor in the wrong slot" and placed it in a correct slot and when you aquire an item
that has already have an item on the same slot it will show a dialog "Would you like to replace the item on your inventory/slot" and the item being replaced will go to your item bank...
