Macros -- %do & print ; Output procedure

This question is from SAS Macro Language 1;

Question :

Reminder: Make sure you've defined the Orion library.

Copy and paste the following macro into the editor. This macro creates a data set named Customer_Freq, which summarizes the variable Total_Retail_Price by Customer_ID. The data is sorted in descending order by the value of Sum. The call SYMPUTX routine creates a series of variables named Top1 through Topx, where x is the value of the Obs parameter.

title;
footnote;
%macro tops(obs=3);
   proc means data=orion.order_fact sum nway noprint;
      var total_retail_price;
      class customer_ID;
      output out=customer_freq sum=sum;
   run;

   proc sort data=customer_freq;
      by descending sum;
   run;

   data _null_;
      set customer_freq(obs=&obs);
      call symputx('top'||left(_n_), Customer_ID);
   run;
%mend tops;

Modify the macro to print a list of the top x customers from the orion.customer_dim data set. Display the variables Customer_ID, Customer_Name, and Customer_Type. Use a macro loop to dynamically generate values for the WHERE statement based on the macro variables Top1 through Topx.
Call the macro with a null parameter value and view the results.

my code:

title;
footnote;
%macro tops( obs=3);
proc means data=orion.order_fact sum nway noprint;
var total_retail_price;
class customer_ID;
output out=customer_freq sum=sum;
run;

proc sort data=customer_freq;
by descending sum;
run;

data _null_;
set customer_freq(obs=&obs) ;
call symputx('top'||left(_n_), Customer_ID);

run;

%do i = 1 %to &obs ;
proc print data = orion.customer_dim;
where Customer_ID = &&top&i ;

run;
%end ;

%macro tops( obs=3);
proc means data=orion.order_fact sum nway noprint;
var total_retail_price;
class customer_ID;
output out=customer_freq sum=sum;
run;

proc sort data=customer_freq;
by descending sum;
run;

data _null_;
set customer_freq(obs=&obs) ;
call symputx('top'||left(_n_), Customer_ID);

run;

%do i = 1 %to &obs ;
proc print data = orion.customer_dim;
where Customer_ID = &&top&i ;

run;
%end ;

%mend tops;

%tops();

My output is in a different format. Can someone help me to get the output in this format.

Top 3 Customers

Customer_ID Customer_Name Customer_Type

10	Karen Ballinger	Orion Club members high activity
16	Ulrich Heyde	Internet/Catalog Customers
45	Dianne Patchin	Orion Club Gold members low activity
