As Tore wrote, _PAGETOTAL is 0 initially. So you say: ... Range 1, 0, what must fail.

If you have run a report infront of this call, _PAGETOTAL will have some value different of 0, and it will work. That's probably the reason it worked in development environment.

If you need to determine the number of pages to print for this REPORT FORM by a previous report, use an IF structure to avoid calling with empty _PAGETOTAL.
