Macro error message

Hi all,

I made some codes including macro. They went well when I used last week, but I always found errors when using them this week

%macro try(missper,n_boot);
%MACRO mi(missper);

data rmse&missper;
		set rmse&missper;
		index = &i;
		
	run;
	%if &i=1 %then %do;
	data poolrmseem&missper rmse_old rmse&missper;
		set rmse&missper;
		index = &i;
		run;
	%end;
	%else %if &i>1 %then %do;
	data poolrmseem&missper;set rmse_old rmse&missper;run;
	data rmse_old;set poolrmseem&missper;run;
	%end;
%mend mi;
%mi(&missper);

   %let i=1;
   %do %until (&i>&n_boot);
	  %mi(&missper);
	  %let i = %eval(&i+1);
   %end;
%mend try;
%try (20, 5);

. Pretty weird!

I have listed the code and log message below. Could anybody help me to find out the reason? Thanks.

Not weird!

Why do you have

%mi(&missper);

in your code before you begin the loop. SAS doesn't hasn't, at that point, created macro variable &i

If you remove that line the code does whatever it is doing.
