Hi, I have an issue with a variable creating an array...

First, I initialize the array.
Code:
@data = []

Then I add the data.
Code:
@data << [...]
Then I display the results
Code:
<% @data.each do |data| %>
It works great... but if I change the variable name to @x it fails and display an empty array...
I dont understand why.
Any help please?
