[SQL] plpgsql and for with integer loopvar error

[Ari Kahn]

I have a single column result that I want to loop through using an 
index. I also want to jump ahead in the result using the index (below: 
i:=i+cluster_cnt-1;) . However, I'm getting the following error.

ERROR:  syntax error at or near "SELECT" at character 9
CONTEXT:  PL/pgSQL function "gets_nooky" line 14 at for with integer 
loopvar

Here is my function ...
CREATE FUNCTION gets_nooky() returns numeric AS
'
DECLARE
    i integer;
    gt1cnt record;
    gt1 record;
    cluster record;
    cluster_cnt integer;
    slocus integer;
    minmax record;
BEGIN
    SELECT INTO gt1 * FROM cgt1;
    SELECT count(*) INTO gt1cnt FROM cgt1;
    FOR i IN 1 .. SELECT count(*) FROM cgt1
    LOOP
        SELECT INTO cluster DISTINCT qry
        FROM seeds2
        WHERE seed IN (
            SELECT qry
            FROM seeds2
            WHERE seed=gt1.seed[i]);
        slocus := i;
        SELECT INTO minmax min(qle) AS mqle, max(que) AS mque
        FROM seeds2
        WHERE seed IN (SELECT * FROM cluster);
        UPDATE locus
        SET locus=slocus, lle=minmax.mqle, lue=minmax.mque
        WHERE id IN (
            SELECT *
            FROM cluster
            );
        SELECT INTO cluster_cnt count(*) FROM cluster;
        i:=i+cluster_cnt-1;
        DELETE FROM cluster;
    END LOOP;
    return i;
END;
'
language 'plpgsql';
Any help is much appreciated!
Thanks,
Ari
