Forms :: How To Deal With Primary Key While Using For Loop In 6i

I am having template table as

template_name varchar2(100) -- primaykey
ex_col varchar2(100)
tab_colvarchar2(100)

Now on the form 6i i've two columns with following data

Column AColumn2 B
-------------------------------------
route a_route
time a_time
id a_id

and a text field where the name of the template will be entered.

e.g.

text filed - testing

In template table i want to insert above values, so template table will look like this

template_name ex_col tab_col
-----------------------------------------------------
testing route a_route
time a_time
id a_id

since tempate_name is primary key, i how should i construct for loop for insert.
