How to validate htmldb_item form item

Question

I have a multiple row form item using htmldb_item.text ( so that a user can enter a quantity for that row item ).
How is validation best handled to ensure that a value is entered for that row?
note: there is also a htmldb_item.checkbox on the row that the user checks to flag that an operation should be done.
Thanks as usual
Bill

for what this is worth:
as scott said, only checked values are passed through from htmldb_item.checkbox'es over to the htmldb_application.g_fNN arrays. that's just how conventional web checkboxes work. if you want to keep your checkboxes in your form, just do their processing in a separate loop. if you're having a hard time keeping the values of your checkbox array matched up with the other htmldb_item values from their corresponding rows, just make sure your checkboxes return values you can use to identify your checked rows. so if you were going against the emp table, i'd suggest having your checked values return EMPNO's...
select htmldb_item.checkbox(1,empno) c from emp
...that way you could more easily match those empno's up with your other htmldb_application.g_fNN values during your page processing.
hope this helps,
