How to Save up the Values after Applying any code into a variable?

i needed help with this code.

I have values of Turbidity in 'y'.

I want this code to Run these questions like, if Y (Turbidity) is less then 5 then save 1 in the output at all 600 vales where there is vale of Turbidity is less than 5.

Same if Turbidity is between 5 to 10 then, Run second conditions and save the value at places wherever Turbidity is from 5-10.

I can't figure out the saving up part.

What is out?

You should pay attention to the colors of strings (purple), because it seems unlikely that you want x = 1, etc. as text.

I find it over the internet, i thought it will work to save the values. What i am trying to do, is i have various vales of a parameter named 'Turbidity'. I want this code to look at those all vales, apply the formula based on the range of the value. For example if Turbidity (y) is 9, the it should run the 2nd part & return the vales in 'x' as = y/5 meaning 1.8.
