How can I use variables in an openquery?

Question

below is my openquery. It works perfect but I need WOADAT range to be dynamic. How can I do that?
SELECT * FROM OPENQUERY(EPAK,
'SELECT WOADAT,WOROUT,BCDESC,WDWO#,BCSIZE,BCCHG
FROM CUST INNER JOIN (BCDE
INNER JOIN (WO2 INNER JOIN WO1
ON (WDCMP = WOCMP) AND (WDCUS# = WOCUS#) AND (WDWO# = WOWO#)) ON (BCCMPY = WDCMP) 
AND (BCSIZE = WDSIZE) AND (BCCHG = WDCHG)) ON (CCMPNY = BCCMPY) AND (CCUST# = WDCUS#)
WHERE (((WOADAT) between 20140501 and 20140531) AND ((WDCMP)=''08''))order by WDWO#')
Any help will be greatly appreciated.

David,
Your statement returned me below error
OLE DB provider "IBMDA400" for linked server "EPAK" returned message "SQL0518: Prepared statement S000001 not found.
Cause . . . . . :   An EXECUTE statement referred to the statement S000001.  S000001 is not a valid prepared statement.  The statement has one of the following conditions: -- The statement has never been prepared. -- The statement identifies
a prepared SELECT or DECLARE PROCEDURE statement. -- The statement was in error at prepare or bind time. -- The statement was prepared in another program or another call of this program and the program was created with CLOSQLCSR(*ENDPGM). -- The statement
was prepared in another module or another call of this module and the module was created with CLOSQLCSR(*ENDMOD). -- The statement was prepared in another call of this program and programs which have run SQL statements have ended and the program was created
with CLOSQLCSR(*ENDSQL). -- The statement was prepared in another call of this module and the activation group ended between calls. The module was created with CLOSQLCSR(*ENDACTGRP). -- The prepared statement was destroyed by a COMMIT or ROLLBACK statement.
This only occurs when connected to a database other than DB2 for IBM i. Recovery  . . . :   Do one of the following: -- If S000001 identifies a prepared SELECT or DECLARE PROCEDURE statement, a different prepared statement must be named in the EXECUTE
statement. -- If the statement had errors, correct the errors and either prepare the statement again or precompile the program again. -- Make certain that S000001 has been prepared in the same program or module call prior to using the EXECUTE statement or
specify either CLOSQLCSR(*ENDSQL), CLOSQLCSR(*ENDJOB), or CLOSQLCSR(*ENDACTGRP) when precompiling the application. -- If the statement was deleted by a COMMIT or ROLLBACK, either specify PREPARE WITH HOLD or bind the program with the correct option to preserve
prepared statements.".
