update multiple rows from a form into a database

I posted a question a few days ago, but no reactions. Here's the thing:
I have a form with a table and the table contains let's say 20 rows. In every row are about 10 textboxes and each row begins with a checkbox. Now I want to save only those rows into the data whose checkboxes are checked. Ofcourse each textform has its own name, but its value can be null.
ANYONE??? PLEASE???
I'm stuck with this problem. Hope my question is clear enough.

-Onno

U must have intialised values for check-boxes for selecting and de-selecting....
b4 executing the insert query u need to compare 2 things whether selected and the corresponding text box has some value....
Hope this works
