counting completed check boxes

counting completed check boxes

Hi!
I am trying to use a spreadsheet to keep track of a sequence of tasks which must be completed for each customer.
I have created columns with the tasks and placed checkboxes in each column under the headings

Can I:

a. count the fill check boxes and have a tally of completed tasks in a column?

b. count the check boxes in groups and change the colour of the box containnig the customers name, according to how faralong the sequence the check boxes have been ticked

If not, is there another way to achieve the same end result?

Also, when trying to attach the document to this forum topic, itdid not show up in the list of Zoho documents. It is the only document so this is something of a surprise. any ideas?

Thanks
Mark
