FRM-40106 Error

Question

I have a form (forms 5) that is called from another (parameter
type) form. Within the new-form-instance trigger, I tell it to
go_block(my_master_block)
and then execute a query. A pre_query trigger reads one of the
parameters passed to the form, and bases the query on that
parameter.
After the query is executed, I then tell it to fill in some of
the detail block fields, based on other parameters that have
been passed.
This all works very well, except that I come up with the error
FRM-40106, which tells me that "there are no navagable items in
my destination block." What this means is that I apparently
have a block (that I am then going to using go_block) in my form
where all the items are neither keyboard navagable nor are they
enabled (according to the online help).
This poses 2 issues:
a) all my fields in all my blocks have been set to be navagable
and enabled, and the error still occurs,
b) I can only find one instance of go_block in my code, right at
the beginning for the master block, and the fields fill in OK.
Has anyone else had this problem?
Many thanks

(Thanks for telling us what the text of 40106 is.)
You will have to debug your form. Put this after each Go_Block command in the form:
Go_block('WHATEVER');
If not form_success then
  Message('go_block whatever failed');
  Raise Form_trigger_failure;
End if;
