Help!

I made this code in the Web Console

model = Sketchup.active_model
entities = model.active_entities
selection = model.selection

if selection.empty?

  UI.messagebox("No Selection")

else

 prompts   = ["X", "Y", "Z"]
 defaults  = ["1.0", "1.0", "1.0"]
 list      = ["", "", ""]
 input     = UI.inputbox prompts, defaults, list, "Size"

  group = entities.add_group selection

 if (group)
  selection.add group
 else
  UI.messagebox "Failure"
 end

 Xsize = input[0].to_f
 Ysize = input[1].to_f
 Zsize = input[2].to_f

 e = selection[0]
 tr1 = e.transformation
 tr2 = Geom;;Transformation.scaling(Xsize, Ysize, Zsize)

 e.transform!(tr1.inverse)
 e.transform!(tr2)
 e.transform!(tr1)

 status = group.explode

end

But, every time I run the script, I get this message in the ruby console:

warning; already initialized constant Xsize
warning; already initialized constant Ysize
warning; already initialized constant Zsize

How do I fix this?

Well, for start, you could type in lowercase Because if your variable name starts with capital letter, ruby takes it as CONSTANT. You are lucky that ruby lets to redefine constants, most of programming languages don't allow . This is why you get the warning.
use something like this, it's easier to read and those are local variables, not constants:

x_size = input[0].to_f
y_size = input[1].to_f
z_size = input[2].to_f

Thanks! it works perfectly now!
