Problem with conditional interaction [SOLVED]

[Grissly]

Well I wandered here for some time and I didn't found anything about it...
The problem is that i make some conditional statement in hotspot interaction, well it's about using inv. items on hotspot... If I use "wrong" item it's fine it displays me a mesage i want to... but if i use proper it displays all i want and last message that was palnned for those Wrong items.

The problem looks as below i hope You'll understand example :
[character uses poster on wall] "Thats fine" [some speach] and  "That doesent work"
[character uses key on wall] "That doesten't work"  The second option is fine but the first one troubles me little.
Is there any way to solve it? other than writing conditional statment for each item used on?

At the conclusion of the "IT WORKS!" section of the actions, add "Stop Running More Commands." It's the second in the list after "Do Nothing."
