DJLIKESGREEN'S PROFILE

I tried to create a variable that my character can't talk to a certain NPC until he's a specified level (3, in this case), so I chose greater than or equal to. To test it out, I set my character's level to 3, and went to talk to the NPC- but he wasn't there. So I tried a bunch of different stuff. Like, I set the character's level to 4. I set it for "greater than 2" and then set his level at 3, and then 4 also, but it still didn't work. But, when I tried "less than 4" it worked.
So, basically, less than or equal to works, but equal to and greater than or equal to don't. Any help?
