Box 3: Forms
Enter the number of the subset in relation to the total number of subsets of forms and continuation forms used. For example, if there is one EX form and two EX/c forms, enter 1/3 on the EX form, 2/3 on the first EX/c form and 3/3 on the second EX/c form.
Where the declaration is made up from two sets of four copies instead of one set of eight copies, the two sets are to be treated as one for the purpose of establishing the number of forms.
