Why would this select statement give an error?

Question

*LOOKUP Z_HELPER
*DIM TGT1 : ACCOUNT="AA_1070100"
*DIM CATEGORY="ACTUAL"
*DIM TIME="2011.JAN"
*ENDLOOKUP
*SELECT(%TGTDEST2%, "[ID]", TARGETDESTINATION, "[UNIQUEIDENTIFIER]"=LOOKUP(TGT))
UniqueIdentifier is a property of Targetdestination dimension. Here is the error its giving:
Validation status of executable file: Failed
- Unclosed quotation mark after the character string '=LOOKUP(TGT'. in:select [ID] from mbrTARGETDESTINATION where [UNIQUEIDENTIFIER]"=LOOKUP(TGT
Validation status of syntax: Failed
- Invalid syntax found; see statements in red

Nilanjan, I changed TGT to TGT1, still same thing.  Here is the big picture outcome I am trying to achieve.
Reporting App
Entity   Costcenter    Shipto   Time          Category  Account    Signed data
ABC        CO1             USA    2011.jan      Actual     ACT123       200
So data is coming in like this, the business wants to set up rules such as.....when Costcenter is CO1 AND Shipto is USA AND Entity is ABC....Change the shipto from USA to INDIA. These rules have to be able to be updated by a business user, So I cant hardcode these rules. My manager doesnt want to use Stored procedures, so here is what I did....
Z_Helper App(Non reporting App)
Entity Costcenter Shipto   signeddata (other required dimensions are just dummy values)
ABC     CO1            USA       9
Now how does 9 get linked to INDIA? I created a new dimension called TARGETDESTINATION. it has ID(which is nothing but shipto country values), and a property called UNIQUEIDENTIFIER. Unique Identifier basically just assigned a unique value to that shiptocountry member row.
So now I need to write a script logic in reporting app that will look up signed data of 9 in this example, and I was thinking use a select statement to pull INDIA from TARGETDESTINATION dimension.
Let me know if you have any suggestions. thanks.
