Does this happen for just you or anybody who fills in the form.
Does any data in the cells appear regardless or the colour i.e are the colours to do with formatting and your rules isn't working?
If you add a dummy row and fill in another colour, does that row and colour appear?
Do other controls work i.e. submit buttons? I'm seeing lots of IE add-ins at the moment interfering with browser forms. - Disable 3rd party add-ins even if they have worked in the past and view the form then.
