dotNet script: interacting with Event editor

Hi, I tried using the dotNet extension for the first time. As a test I thought I'd start with a simple script and trying to make the script interact with the Event editor. But I just can't seem to make it work.
Here's what I did step by step:
1-Put a dotNet extension on the frame editor.
2-Enter the following script:

using MMFInterface;


class class1
{
	public void lolString()
	{
		Conditions.CallImmediateCondition("setString",null);
	}
}

3-Add a string object on the Frame editor
4-Add event:
+Upon pressing "Enter"
-call function: class1.lolString with parameters ("")

5-Add event:
+InteractedImmediateCondition ("setString")
-Set String to "lol"

6-I try start the app and press Enter...and nothing happens. The string doesn't turn into "lol".

What am I doing wrong?

Ahh, I see. I missed that. Thanks a lot.
