Cant add extra amount with EDD_Fees class

Im using EDD_Fees class for adding extra fee to products, Iv’e used this class before and it works like charm but now i can’t figure it out why amount is 0 (it seems returning null)
Here is my full class code

	$feeid_gen = date("Ydhis") . $download_id;
			function cencored_function() {
			// Additional Services Price START here
					$cencored_fee = array(
			'amount'      => $int_val,
			'label'       => 'hbbl',	
			'id'          => $feeid_gen,	
			'no_tax'      => false,
			'type'        => 'fee',
			'download_id' => $download_id,
			'price_id'    => NULL	
				);
			EDD()->fees->add_fee( $cencored_fee);
			/// Additional Services Price END here
			}
			add_action( 'init', 'cencored_function' );
			cencored_function(); // Runned
