I wish to show/hide some labels and fields depending on if the current report page is the last one (ie: show a "subtotal" label from page 1 to n-1, and "total" label at page n, the last one).
I know current page can be get using SRW.GET_PAGE_NUM; I also know that I can bind a numeric field to current page and total pages number (Property inspector. Source: page number/total pages). But I could not be able to use them in format triggers.
I created F_CURR_PAGE and F_TOT_PAGES fields, and they show current page and total report pages number.

/forum/fa/14619/0/

If I use them into a format trigger (ie: IF F_CURR_PAGE < F_TOT_PAGES THEN...) I got "identifier F_CURR_PAGE must be declared". how can I use theese parameters into format trigger?
thanks

Fields are referenced with a colon sign in front of their names, e.g.
IF :F_CURR_PAGE < :F_TOT_PAGES THEN...

I tried it, getting error "REP-0730: the bind variable is not defined" (see pic)

Where exactly did you create F_CURR_PAGE and F_TOT_PAGES? In Data Model Editor? If not (but in Paper Layout Editor), try to do so.

I created fields in layout editor. I dont know if it is possible to create them in data model (I think they should be formulas, but I dont know how should they be calculated)

(Sorry for being late.)

You're right, it seems you can't create it in Data Model editor. I don't have other ideas, unfortunately.
