Access Query without VBA
===

I have a question regarding a database query on unrelated tables.  
It is required that VBA isn't used this time (requirement from my manager), which makes it hard.  

My query must return 5 columns of data. 
The first 4 columns are directly retrieved from the Output of a previous query, so that is easy. 

    Query Q_STOP_LOSS: 
    
    Year  Contr_Pool_ID          Contr_Ins_ID      COUNTRY   Employees    STOP_LOSS
    2010  Crédit Agricole CIB    QUATREM           2         6024
    2010  Crédit Agricole CIB    QUATREM           2         6024
    2010  Amada CO LTD           MALAKOFF MEDERIC  4         1320
    2010  Amada CO LTD           MALAKOFF MEDERIC  4         1320
    2010  Amada CO LTD           MALAKOFF MEDERIC  4         1320

The last column called "STOP_LOSS" is the problem because the value filled in there should be retrieved from an unrelated table based on a WHERE clause. 
It should contain the SL value from another table that does not contain equal fields. 
The table is called T_STOP_LOSS and lists intervals. 
    
    Table: T_STOP_LOSS

    ID   LIVES_FROM LIVES_TO  NR_COUNTRIES_FROM  NR_COUNTRIES_TO  SL_VALUE
    1    0          999       2                  2                39,3
    12   0          999       3                  3                34,6
    23   0          999       4                  4                29,6
    34   0          999       5                  9                25,7
    45   0          999       10                 100              22,17
    46   1000       1499      2                  2                31,1
    2    1000       1499      3                  3                27,4
    13   1000       1499      4                  4                23,3
    24   1000       1499      5                  9                20,4
    35   1000       1499      10                 100              17,5

When the values for "Country" and "Employees" (columns 3 & 4, being the results of previous queries) lie in the interval between respectively "LIVES_FROM/LIVES_TO" AND "NR_COUNTRIES_FROM/NR_COUNTRIES_TO", then what should be returned needs to be the corresponding SL_Value. I can't figure it out since there are no corresponding fields between the two tables and I'm not allowed to use VBA this time. 
To make it harder, "LIVES_FROM/LIVES_TO" and "NR_COUNTRIES_FROM/NR_COUNTRIES_TO" contain the ID of a related table.  
Any idea how I can get add this column to the query without using VBA... ? 
I attempted to use the Query tool and also SQL view, but I was unable to achieve a proper result (with VBA it would be a lot easier and I am not the most handy one with Access on its own...).  

Let me know when my question is not clear!
