SQL Newbie

Help!!
I am using embedded SQL to Create a table, going through RPG calculations
after a select statement, then moving my desired values into Host Variables
which I then am trying to insert into my newly created table. I have tested
these statements in ISQL with success which is why I am lost as to how come
it is not working in my RPG program. Any help would be greatly appreciated. 
I have looked up the following SQLcode/SQLstate errors:
-7708 &1 in &2 not valid for operation
55019 Table is in an invalid state for the operation. 
CODE:
DS
            1  2 Keysta
            3  3 Taxsta
         P  4 100Ordnum 
         P 11 160Cusnum 
           17 46 Cusnam
         P 47 552Taxamt

/EXEC SQL
CREATE TABLE ARPC008
  (KYSTT CHAR(2),
   TAXTS CHAR(1),
   ORDNO DEC(7,0), 
   CUSNO DEC(6,0),
   CUSNM CHAR(30),
   TAXTL DEC(9,2),
/END-EXEC

*GOES THROUGH Select statement, CALCULATIONS, POPULATES
DATA STRUCTURE WITH DESIRED VALUES.

(this is where I am popping up with the error code in ISdebug)
/EXEC SQL
INSERT INTO ARPC008
       (KYSTT,
        TESTS,
        ORDNO,
        CUSNO,
        CUSNM,
        TAXTL)
VALUES
      (:Keysta,
       :Taxsta,
       :Ordnum, 
       :Cusnum, 
       :Cusnam,
       :Taxamt)
/END-EXEC
