Subject:      Calling Global Variables Conditionally from a Nested Macro

I would appreciate any help in calling global variables conditionally
from a nested macro.  The program structure is similar to the following:
 
%global COUNT1 COUNT2 COUNT3 COUNT4 COUNT5;
%macro one (parameters);
 
   macro statements;
   call symput statements to set up global vars;
 
   invoke macro 2 with parameters 1, 2, 3, 4, or 5, depending on which
   global count variable is needed;
%mend macro 1;
 
%macro2 (countparameter);
 
   %if &count&countparameter > 0 %then %do;   e.g., &count3
     program statements;
   %end;
%mend macro2;
 
 
I would appreciate help with the %if statement - how to have the macro
variable be read as &count1 to &count5, depending on invocation.
