Unable to read hash value in Powershell 1

[JustScriptIt]

I am writing a simple script to get more familiar with powershell.

This script reads input parameters into a hash

$states = @($args)
$states
write-host Color is $states.color

On the command-line, I set the following values$shape = 'circle'; $color = 'pink'; $size = 'large'I then invoke the program with the following command

.\shapes_n_colors.ps1  $shape $size $color

And, I get the following output:

circle
large
pink
Color is

I am unable to figure out why $states.color is blank. I was expecting the output "Color is pink"

I am following this artical,

Where am I going wrong???

I pretty new to all of this so hopefully someone smarter than me can chime in...
But here is what I see

Enclose the hash table in braces ({})

You're using parenthesis.

Secondly, you don't have any attributes assigned to your object, yet you're trying to reference them. The way I'm looking at it, the script would think "circle", "large", and "pink" are states. I don't know the syntax but generally speaking I think it would go like this:

In the script you would have to acquire the values then assign them to the attributes
$states[1].shape = $shape
$states[1].size = $size
$states[1].color = $color

write-host Color is $states[1].color

.\shapes_n_colors.ps1 $shape $size $color

Again, I don't know the syntax, so I don't know if you need to declare the number of attibutes each object will have or what. Hopefully this will help you enough so you can figure it out.

Okay I played with this a bit and here is what I came up with:

param($shape,$size,$color)
$states = @{Shape=$shape; Size=$size; Color=$color}
$states
write-host "Color is "$states.Color

Call it like you did above: .\shapes_n_colors.ps1 $shape $size $color
