Not able to change random range in cell 23

[AmmeySaini]

I tried changing the random range for my negatives and activates from 0, 4 to 0, 9 it worked fine but when I'm changing it to 0, 11 it just get stuck there (for 0, 9 it works very fast but for 0, 11 it just get stuck)

because you don't let range to introduce the activate word... and the while statement continues to infinite
