coding multicolumn check boxes

[Nick Hoare]

Hi, I am wondering if anyone can tell me how to go about coding a
multicolumn check box? I want one check box per row, and want to be able to
populate it with data from a table. Basically like what the Hotmail "inbox"
etc, looks like. i don't know how to iterate through rows and format the
columns...
hope someone can help.

Thanks,
Nick.
