Forms :: Fields Not Writing To Database Table

I have an Oracle Form 6i. There are two blocks. One is a database block called CUSTOMER and the other is a non-database block called CONTROL.

In the PRE-INSERT trigger of the database block, values from the non-database table block are passed to the database table block. When I pass values I use the :BLOCK_NAME.field_name eg. :CUSTOMER.scale_code := :CONTROL.scale.

In this form the values passed to the database block from the non-database block in the PRE-INSERT trigger do not use the block name e.g. :-

:warehouse := :global.default_warehouse;
:capturer :=captured
:scale_code := scale;
:date_captured := sysdate;
insert into dd_audit(cus_id,cap_date) values(:CONTROL.cus_id,SYSDATE);

This application used to work fine for months, last week when writing the values in the PRE-INSERT trigger, just the warehouse field had a value. The remaining fields after the warehouse did not pass any values, although it was verified that values would have been present in the non-database block. The date_captured field should have at least had the system date. The last insert into dd_audit was successful.

I have done numerous tests on our test database and could not replicate the problem. Would passing the values from the non-database block to the database block without the :BLOCK_name preceding the field name cause this problem.
