Using conditions to change position on page

Hi,

I have referred to the manual and would like to use the condition to adjust the position of a table on the second page of a document, etc.

My question is, though, can I set a value for the last page? I have tried Cond(Page()=1,145,270,145) but this does not work. I need the last page to return to the values of the first page, to allow for an invoice totals box to be used.

Thanks in advance for any help!
