I got to this, and this is apparently the weirdest SSRS error. When you move the sub file inside a list or rectangle and add a page break, SSRS flips the date format of the date parameters and, therefore, you end the transfer of values ββthat SSRS does not recognize as dates.
Even more obscure. If you pass the date values ββso that the report succeeds, the next time you run it, SSRS will flip them the other way, and then they will remain flipped that way until you exit the report.
Return to the report and repeat the steps above. I will bring this up to Microsoft Connect.
