Parent table is income:

db.define_table('income',
   Field('client' , requires=IS_IN_DB(db, db.client.id), writable=False),
           ....
   Field('source', requires=IS_IN_SET(DEBTOR_TOGGLE_NO_BOTH),))

Child Table is deductions:

db.define_table('deductions',
   Field('client' , requires=IS_IN_DB(db, db.client.id), writable=False),
           .....
   Field('Income_Src', 'reference income', requires=IS_IN_DB(db, 
db.income.id, '%(Employer_Name)s')),
   Field('Additional_Description' , 'string', length=50))

deductions.Income_Src references income.

When I delete an income source, it doesnt cascade.....What am I missing? (I 
know this is an easy question, but I cant find the answer anywhere)
