trigger scripting

Okay. This sounds really easy to do, but I am confused.
What I am trying to do is make a script that goes with this trigger:

You suddenly perceive the vague outline of an aura of rebounding around *.

Now, I want to to set the wildcard to a variable. So let's say the person is Bob.

You suddenly perceive the vague outline of an aura of rebounding around Bob.

Now, I am not getting any errors when it goes through, so I know nothing is wrong with the script... except that instead of saving "Bob" to a variable, it says "Bob."
I am looking for a way to remove the "." from the variable definition.

I have been messing around with it and apparently, the thing I copied and pasted was not the same, so I managed to fix it. Sorry for taking up space.

Could you copy and paste the exact trigger here? (go to the trigger dialog box, highlight this trigger, click copy, come here, click paste, put it in code tags, you probably won't have to escape anything if it's a simple trigger, but you can do that via MC as well).
