Perfect! It worked.

Now, the only problem is that it is giving the result as "2". Can I set it so that it will convert the result, so that it appears as "ii"?

Right now it is showing as "Page 2 of ii". I need it to show as "Page ii of ii".

Normally, when I highlight a page number field and right click on it, among the options are "Edit Field", and there one can set the format of the result to Arabic, Roman numeral, etc. But when I highlight the result of the calculated field we are discussing, the "Edit Field" option is grayed out. Is there another place where I can set the format of the resultant number?
