It seems your code is something like

Array.push 'a'

This doesn't work because push is an instance method of the Array class, that 
is: you need to call it on an individual array (an instance of class Array), 
not on the Array class itself. This is how you should do it:

a = Array.new

a.push 'string'

or 

[1,2,3].push 4

(the syntax [1,2,3] creates an array, instance of class Array, containing the 
items 1, 2 and 3).

I hope this helps
