'Select INTO" in Execute (dynamic query )

Hi

What's wrong with this code (ERROR: syntax error at or near "INTO" at
character 8)?

Problem: I want to put A1, A2 values in two variables vara, varb.

CREATE OR REPLACE FUNCTION test(text)

RETURNS VARCHAR AS $$

Declare

vara VARCHAR(10) :='';

varb VARCHAR(10) :='';

result VARCHAR(10) :='Result';

BEGIN

EXECUTE(

'Select INTO vara, varb A1, A2 from '|| $1

);

RETURN result||': '|| vara ||' '|| varb;

END;

$$ LANGUAGE plpgsql;
