In my shop I have a special offer which allows the buyer to get 10 items at a discount. Instead of manually selecting each individual product item I get my user to select "special 10 pack" item. I have then set up a form (using checkboxes) so my buyer has to checkbox the 10 items they want. I have a list of 30 in the form. I would like the form to only allow 10 checkboxes to be selected.Can anyone help? @remindables
