No Beats/Notes Appear

I'm working on a rhythm game called BEATZ, and I'm using a system that uses a variable, every 1-3 seconds the chord changes to a new number between 1 and 6. Each number represents a chord. But when I start the song, the beats aren't coming up (there are 3 beats: red, green, blue) Could somebody help me, it would be appreciated.

Here's a screenshot of the code I'm using to generate the notes.

random(1,6) returns a number with decimal point, like 2.2947030939

If you need an integer number use these expressions:

int(random(1,7))

or

choose(1,2,3,4,5,6)

Oh, okay. It worked. Thanks!
