Merge rows

Question

Hi everyone
Im using toad for oracle version 9.6.And preparing a script to count the number of employees available per division and per section.
Now i manage to convert the rows into columns and my output look as follows.
Division Number Of employees ICT Section IA section
CSD 45 45
CSD 10 10
However i want the results to be as this one below:
Division Number Of employees ICT Section IA section
CSD 55 45 10
You can hav a look on this coding , i used procedures since there is no specific table containing this data
select xxx.get_org_div(p.org_id,p.business_group_id) division,
count(a.employee_number) Number Of employees ,
decode(xxx.get_org_sec(p.org_id,p.business_group_id),'ICT',count(a.employee_number),null) ICT Section
decode(xxx.get_org_sec(p.org_id,p.business_group_id),'IA',count(a.employee_number),null) IA Section
from employees a,assignment p
where a.person_id = p.person_id
group by xxx.get_org_sec(p.org_id,p.business_group_id),
xxx.get_org_div(p.org_id,p.business_group_id)
and i have tried this one but it gives an error,'Not a single-group group function'
select xxx.get_org_div(p.org_id,p.business_group_id) division,
count(a.employee_number) Number Of employees ,
max(decode(xxx.get_org_sec(p.org_id,p.business_group_id),'ICT',count(a.employee_number),null) ICT Section
max(decode(xxx.get_org_sec(p.org_id,p.business_group_id),'IA',count(a.employee_number),null) IA Section
from employees a,assignment p
where a.person_id = p.person_id
group by xxx.get_org_sec(p.org_id,p.business_group_id),
xxx.get_org_div(p.org_id,p.business_group_id)
Thanking in advance
