serial print problems for tcs34725 color sensor

Hallo everyone!!
I’m running into a problem with the serial print of my definition. I’m using a tcs34725 color sensor: after having adjust the saturation I would want to convert and print the RGB values into HSL.
Since I’m an entry level Arduino user I really don’t understand where is the mistake…Does anyone can help me please???
Thanks a lot !!!
