Hi and thanks for your replies.
The fix was as per
Andreas' post and this works now.
Although, I would like to improve the code and make it better.
The ' business_name_business_name_seq' is just a sequence type for the table business_name where business_name table is related like:
business_name -> business_address by the business_name_id
as the submit form is just one form, i inserted the values in order so I needed the fk_business_name_id to be taken from the previous insert and so on...
perhaps there is better way to do this.
cheers

can you replace:
business_name_business_name_seq.last_value
with:
(select last_value from business_name_business_name_seq)
or, more defensively coded:
(select max(last_value) from business_name_business_name_seq)
i am assuming business_name_business_name_seq is some kind of one-row
table that is always guaranteed (how?) to have one row and sort of fakes
a sequence (which brings the question of why not use a true sequence?)
