How do I use "is between values" correctly?

Hi, all!

I have a problem which I haven't been able to solve myself for a long time:

In the game, the enemies come in waves, and I want to achieve, that in every third wave comes a boss. I haven't make a boss yet, but I made a global variable named WaveCounter which counts the current wave in numbers, and when the value is equal to 3 there shouldn't come another wave of enemies because only the boss will come (when I'll make it).

I've tried two ways to resolve, that the things work the way they should, but in both versions, the enemies come even when WaveCounter is equal to 3.

I made a simple example for both versions, to show you what the problem is (these are my first Google Drive sharings, I hope everything is ok):

Anyone knows what's the problem?

I don't see a problem here? You set WaveCounter to 1 when WaveCounter is > 3, so it reverts back to the start of the game. If you want it to go somewhere else then don't set WaveCounter to 1.

This is not the problem, the problem is when WaveCounter is 3 there shouldn't happen anything, enemies come when they shouldn't.

Take out the 0.1 second wait.

So far it seems working. Thanks!
