Pathetic Question about Inventory Objects

[rtf]

OK, this is probably one of the stupidest questions ever, but It's not something that would be in the manual.

When my player picks up an object, everything goes fine, but when I open up the inventory screen, all I see is a blue cup.
YES... I HAVE set the inventory object image to the image that i want to be seen in the inventory.  I'm not that dumb to forget to do that.

So I was wondering if someone could give me a hand

Have you made sure you didn't mix up room objects and inventory objects? If you pick up a world map, for example, it may be room object 4 but inventory object 2. In this case, you'd have to script

ObjectOff(4);
AddInventory(2);
