Forms :: Map Excel Columns On Oracle Forms And Insert It Into Database

I have task. I am using oracle forms 6i. I want to import excel data to oracle forms(its common task using ole2 package). But this time I want to map the columns i.e my database table having 5 columns. and the excel file is having 2 or 3 columns then i suppose to map those columns and accordingly insert it to my table.

So far i have import column heading of excel to oracle forms, then i've provide list item for mapping each column. so that user can map excel column to database columns. Now I am confuse how to write the code so that selected columns should get inserted into database.

-more details

I have table with columns id, name, location, address, plan. in those columns i need to insert records form excel. user having a excel with 3 columns col1, col2, col3. on the form i've fetch column headers of excel and in front of that i've provide database column list , so user can match excel column with database column. e.g.

COL1 --> list value of database column
COL2 -->list value of database column
COL3 -->list value of database column

Once user map those column i want to insert those values into my database table (table with columns id, name, location, address, plan). and i am confuse about this code.
