that works, but there's another error message:

X Error (line 153): undefined symbol 'eModeUseInv'

Again, if it changes anything, i'm using version 3.0.

I moved it to the place you said to, but now it says:

X Error (line 152): undefined symbol 'eModeUse'

I entered that but now at the bottom it says:

X Failed to save room room3.crm; see details below
X Error (line10): undifined simbol 'button'

also, I know I don't have an Inventory Item iat.

No, "Handle inventory-clicks in script" is set to false. Oh and i have version 3.0 in case that changes anything.

no displays are showing. how do I fix it?

Yes, I've already tried that. It doesn't do anything.

Well, now it's letting me test the game, but I can't seem to exchange the two items while i'm testing.
I copied in exactly what monkey_05 _06 suggested, but if I try using itwenty on igambleliscence, or doing anything else, I don't lose itwenty or get igambleliscence. 

basically, here is the script i have:

function oObject0_UseInv()
{
player.AddInventory (igambleliscence*itwenty);
}

I tried to save, but at the bottom of the page it says:

X Failed to save room room3.crm; details below
X Error (line 10): Operator cannot be applied to this type

I'm trying to use itwenty on oObject0 to get igambleliscence. Any suggestions?
