Error while adding UUID into a table via dynamic sql

I want to add uuid into a table using dynamic sql.Hier is my Code:

CREATE OR REPLACE FUNCTION "Surrogate_gen"(tblname text) RETURNS void AS
$BODY$DECLARE 
uid UUID;
tablename text;
BEGIN
uid:=(select uuid_generate_v1());
tablename:=tblname;
execute 'INSERT INTO public."'||tablename||'"(surrogate) VALUES('||uid||')';
END
$BODY$
LANGUAGE plpgsql

but an error occured like this: INSERT INTO public."produkt"(surrogate) VALUES(ed520ad0-5aba-11e2-961b-1c4bd605a98d) Syntaxerror: »aba« that is in my uid

If I dont use Dynamic sql It is possible to add uuid in this table. Would please say me why this error occures? Thank you

The easiest is to just move the select to inside the string:

BEGIN
tablename:=tblname;
execute 'INSERT INTO public."'||tablename||'"(surrogate) select uuid_generate_v1()';
END
