ERROR 180-322: Statement is not valid or it is used out of proper order.

When I want to run this macro:

%macro prep_graph(Tab_Input=,stat=,var=);
proc transpose data=&Tab_Input out=&stat._&var._PRE(drop=_name_);
by RatingClassFirstAv;
id Age;
var &stat._&var.;
run;

proc transpose data=&stat._&var._PRE out=&stat._&var._graph
(rename=(_NAME_ = Age));
id RatingClassFirstAv;
run;

proc sql;
create table &stat._&var._graph as
select input(Age, 4.) as Age, *
from &stat._&var._graph ;
quit;

proc sort data=&stat._&var._graph ;
by Age;
run;

proc transpose data=&stat._&var._graph out=&stat._&var._PRE (rename=(_NAME_ = RatingClassFirstAv));
id Age;
run;
%mend prep_graph;

%prep_graph(Tab_Input=Stat, stat=Avg, ,var=PD);

I've got an message:

WARNING: Apparent invocation of macro PREP_GRAPH not resolved.

ERROR 180-322: Statement is not valid or it is used out of proper order.

And when I run everything without macro, it works perfectly.

How to resolve it?

You have entered a missing surplus argument invoking the macro

%prep_graph(Tab_Input=Stat, stat=Avg, ,var=PD);

replace with

%prep_graph(Tab_Input=Stat, stat=Avg,var=PD);
