please give me the complete SQL to make an if-statement (with the field name "T/C") based on the following criteria and add it to  the attached code snippet
1.  if the field called "cust_ID" is not null in both "table C and table T, then I want the record to say "C/T"
2.  if  "cust_ID" is null in table C, but not null  in table T, then I want it to say "T"
3. if  "cust_ID" is null in table T, but not null  in table C, then I want it to say "C"

thank you very much
SELECT M.cust_ID
FROM qryConverterTransCustomers_01 AS C RIGHT JOIN (qryConverterTransCustomers_02 AS T RIGHT JOIN tmpMasterTable AS M ON T.cust_ID = M.cust_ID) ON C.cust_ID = M.cust_ID;

Will c.cust_id AND t.cust_id ever be null?  If so, neither will be displayed with this query.  Regardless, this should handle C, T or T/C.

SELECT M.cust_ID
,iif(c.cust_id is not null, iif(m.cust_id is not null, 'T/C', 'C'), iif(m.cust_id is not null,'T','NEITHER'))
FROM qryConverterTransCustomers_01 AS C RIGHT JOIN (qryConverterTransCustomers_02 AS T RIGHT JOIN tmpMasterTable AS M ON T.cust_ID = M.cust_ID) ON C.cust_ID = M.cust_ID;

the purpose of the if statement is to tell me if csut-ID is present in either table T or C. the if statement should not contain table M.  
1.  if the field called "cust_ID" is not null in both "table C and table T, then I want the record to say "C/T"
2.  if  "cust_ID" is null in table C, but not null  in table T, then I want it to say "T"
3. if  "cust_ID" is null in table T, but not null  in table C, then I want it to say "C"

thank you very much

Got it.  And do you want t/c or c/t.  Because you said t/c at first and c/t now.  Or doesn't it matter?

This should do it.
SELECT M.cust_ID
,iif(c.cust_id is not null, iif(t.cust_id is not null, 'T/C', 'C'), iif(t.cust_id is not null,'T','NEITHER'))
FROM qryConverterTransCustomers_01 AS C RIGHT JOIN (qryConverterTransCustomers_02 AS T RIGHT JOIN tmpMasterTable AS M ON T.cust_ID = M.cust_ID) ON C.cust_ID = M.cust_ID;
