SAS macro variable with conditions

[Myurathan]

Hi experts,

I have the following macro and I want the macro to assign correct values.

%Macro Month_Pre_Selection (close, period1);

%if &Close. = 1 %then %do;

	%let input_contracts = CONTRACT_&period1.; 
	%let input_customers = CUSTOMER_&period1.;
	%let input_object = OBJECT_&period1.;
	%let input_payplan = PAYMENTPLAN_&period1.;

%end;

%if &Close. = 2 %then %do;

	%let input_contracts = CONTRACT_&period1._PRE; 
	%let input_customers = CUSTOMER_&period1._PRE; 
	%let input_object = OBJECT_&period1._PRE;
	%let input_payplan = PAYMENTPLAN_&period1._PRE;

%end;

%mend;

when I run it with following code 

%Month_Pre_Selection (1, 201805);

%put &input_contracts;

I get the following message in the log

WARNING: Apparent symbolic reference INPUT_CONTRACTS not resolved.
&input_contracts

What am I doing wrong?

Thanks in advance.

%Macro Month_Pre_Selection (close, period1);
%global input_contracts ;

Or move the %PUT statement inside the macro.
