How to use title variable inside a class?

I try to define a class by myself and I want to put title to top-center of page but when I use it like

chead{textcolor{blue}{textbf{ {fontfamily{phv} selectfont @title}}}}

it does not print title to its position.

I use maketitle command in document. I read it that it locks the variable.
So how could I create my class so that it will print the title to page’s top-center as a variable?

EDIT:Changed document class from article to report and it is solved.
