LOOKUP for accounts in %ACCOUNT_SET%

Question

Hye.  I try to do a easy scriptlogic  but I get error.
I have an input report witth  3 accounts (5700,5710,5720) as lines and 2009.JUN and 2009.JUL as columns.
I introduce data in month 2009.JUL in input report  and I use LOOKUP in a Script Logic Default in order to get the data  of 2009.JUN for each account from other cube "FINANCE".
The default code is:
*LOOKUP FINANCE
     *DIM ACCOUNT="%ACCOUNT_SET%"
     *DIM CATEGORY="BUDGET"
     *DIM JUN:TIME="2009.JUN"
*ENDLOOKUP
*XDIM_MEMBERSET ACCOUNT=5700, 5710, 5720
*WHEN CATEGORY
        *IS  BUDGET
               *REC(EXPRESSION=LOOKUP(JUN), TIME=2009.JUN, ACCOUNT)
         *ENDWHEN
*ENDWHEN
*COMMIT
I want to make a LOOKUP for each account (5700, 5710, 5720) to Cube FINANCE but  when I push "Send Data" I get the next error: "Error running default logic (Member "5700,5710,5720" not exist"".
I think that the LOOKUP considers that  DIM ACCOUNT is "5700,5710,5720" all together,  so I get an errror.
How can I do it?

Thanks Seldon but It doesn´t  work.
I validate default script with your code  and I get an error:  Multi LOOKUP in the same cube not allowed.
I use the next code and when i push sendata in my report, I get an error : Error running default logic (Member "%ACCT%" not exist.
*LOOKUP FINANCE
*DIM ACCOUNT="%ACCT%"
*DIM CATEGORY="BUDGET"
*DIM JUN:TIME="2009.JUN";
*ENDLOOKUP
*XDIM_MEMBERSET ACCOUNT=5700, 5710, 5720
*FOR %ACCT%=5700,5710,5720
*WHEN CATEGORY
*IS BUDGET
*REC(EXPRESSION=LOOKUP(JUN), TIME=2009.JUN)
*ENDWHEN
*ENDWHEN
*COMMIT
*NEXT
