New to LISPs, trying to create a layer LISP

[etilley327KA]

I've tried multiple variations I found on the web, but to no avail. This is the latest version I have.

I'm trying to turn off one layer and change the color of two other layers.

Also, does anyone know if there is a way to increase the size of the text in a layer?

Any help would be appreciated, thanks.

(defun C:FC ()
