How to write nested cursor for Adv. Collections dunning letter query

Question

I am trying to write a query for Advanced Collections duninng letters. Some accounts for this customer have invoices for more than one currency. In order to find all of the invoices this query works:
select to_char(sysdate, 'MM/DD/YYYY') currsysdate,
decode((per.person_first_name || per.person_last_name), null, ARPT_SQL_FUNC_UTIL.get_lookup_meaning('RESPONSIBILITY', 'APS'), per.person_first_name) first_name,
per.person_last_name last_name,
org.party_name org_name,
loc.address1 address1,
loc.address2 address2,
loc.city city,
loc.state state,
loc.postal_code postal_code,
per.person_first_name first_name1,
(select sum(aps.amount_due_remaining)
from
iex_delinquencies_all dd,
ar_payment_schedules_all aps
where
dd.payment_schedule_id = aps.payment_schedule_id and
dd.party_cust_id = org.party_id and
dd.cust_account_id = 255849 and
dd.customer_site_use_id = 13071) total_amount_due_remaining,
to_char(sysdate+7, 'MM/DD/YYYY') required_pay_date,
rs.source_email collector_email,
arc.alias collector_name,
arc.telephone_number collector_phone,
ar.account_number,
cursor
(select
ct.trx_number invoice_number,
to_char(ar.due_date, 'MM/DD/YYYY') due_date,
ar.amount_due_remaining amount_due_remaining,
ar.invoice_currency_code invoice_currency_code
from
iex_delinquencies_all d,
ar_payment_schedules_all ar,
ra_customer_trx_all ct
where
d.party_cust_id = org.party_id
and d.cust_account_id = 255849
and d.customer_site_use_id = 13071
and d.payment_schedule_id = ar.payment_schedule_id
and d.status = 'DELINQUENT'
and ar.customer_trx_id = ct.customer_trx_id
and ar.amount_due_remaining <> 0
) as payment_history
from
HZ_LOCATIONS loc
,hz_parties org
,hz_parties per
,jtf_rs_resource_extns rs
,ar_collectors arc
,hz_cust_accounts ar
where
loc.location_id = 11600
and org.party_id= 255849
--and per.party_id = nvl(:CONTACT_ID, org.party_id)
and per.party_id = 255849
and arc.resource_id = rs.resource_id
and rs.RESOURCE_ID = 100022224
and ar.cust_account_id = 182399
But this assumes there is only one invoice currency but there isn't. Now I need to loop through all the distinct currencies in the ar_payment_schedules table so I was trying something like this:
select to_char(sysdate, 'MM/DD/YYYY') currsysdate,
decode((per.person_first_name || per.person_last_name), null, ARPT_SQL_FUNC_UTIL.get_lookup_meaning('RESPONSIBILITY', 'APS'), per.person_first_name) first_name,
per.person_last_name last_name,
org.party_name org_name,
loc.address1 address1,
loc.address2 address2,
loc.city city,
loc.state state,
loc.postal_code postal_code,
per.person_first_name first_name1,
(select sum(aps.amount_due_remaining)
from
iex_delinquencies_all dd,
ar_payment_schedules_all aps
where
dd.payment_schedule_id = aps.payment_schedule_id and
dd.party_cust_id = org.party_id and
dd.cust_account_id = 255849 and
dd.customer_site_use_id = 13071) total_amount_due_remaining,
to_char(sysdate+7, 'MM/DD/YYYY') required_pay_date,
rs.source_email collector_email,
arc.alias collector_name,
arc.telephone_number collector_phone,
ar.account_number,
cursor
(select distinct ar.invoice_currency_code invoice_currency_code
from
iex_delinquencies_all d,
ar_payment_schedules_all ar,
ra_customer_trx_all ct
where
d.party_cust_id = org.party_id
and d.cust_account_id = 255849
and d.customer_site_use_id = 13071
and d.payment_schedule_id = ar.payment_schedule_id
and d.status = 'DELINQUENT'
and ar.customer_trx_id = ct.customer_trx_id
and ar.amount_due_remaining <> 0
cursor
(select
ct.trx_number invoice_number,
to_char(ar.due_date, 'MM/DD/YYYY') due_date,
ar.amount_due_remaining amount_due_remaining,
--ar.invoice_currency_code invoice_currency_code
from
iex_delinquencies_all d,
ar_payment_schedules_all ar,
ra_customer_trx_all ct
where
d.party_cust_id = org.party_id
and d.cust_account_id = 255849
and d.customer_site_use_id = 13071
and d.payment_schedule_id = ar.payment_schedule_id
and d.status = 'DELINQUENT'
and ar.customer_trx_id = ct.customer_trx_id
and ar.amount_due_remaining <> 0
and ar.invoice_currency_code = invoice_currency_code
) as payment_history
) as g_currency
from
HZ_LOCATIONS loc
,hz_parties org
,hz_parties per
,jtf_rs_resource_extns rs
,ar_collectors arc
,hz_cust_accounts ar
where
loc.location_id = 11600
and org.party_id= 255849
--and per.party_id = nvl(:CONTACT_ID, org.party_id)
and per.party_id = 255849
and arc.resource_id = rs.resource_id
and rs.RESOURCE_ID = 100022224
and ar.cust_account_id = 182399
But I am getting missing right parenthesis error which leads me to think I am writing this correctly.
