On the bottom line, I won’t allow me to set a decimal as an increment, I am pretty new to this thing. Couldn’t think of any solution. I tried creating a new int such as , that would not work either.

Integers don’t have decimals. If you create a float variable with float perSec it should work.

Oh I see, I set perSec as an integer at the beginning chaning them to Float solved the issue. Thanks!
