Cascading prompt not working

[reyesryder]

Hi,
 I have a cascading prompt. When I am trying to use on same report page, it results in no data.
  When I use it on  a separate prompt page, it works well. Alternately it works when I take out the cascade option on main page itself.

Any update on why this is happening?

Did you set Auto submit = true on the source prompt?
