Validation failing, and loosing data input in checkbox

Hi,
In my form is a repeated table area, which outputs checkboxes for each record in a particular table.
In my form I have added validation, where a price has to be inputted as an integer, when the validation fails, using the excellent video tutorial on the site, I have set my form up so for all select and text boxes, the data is retained on the form. However, I cannot do the same with my repeated table checkboxes.
When I try and select the value in dreamweaver to make the field checked/unchecked, the repeated checkboxes do not show in the list of available fields. Presumably because the fields are in a repeated table?
I'm at a loss as to what to do. Will I need to play with the code, or does data assist accommodate this?
Thanks and look forward to your reply,
Aled
