Moji:
let me know if I am not explaining this whole thing correctly.
You are absolutely not explaining this at all clearly.
There are many points that might cause this behaviour, but as you give no real information about what you actually do have in the design of the report we could spend a long time guessing one after the other.
Alternativlely, you could actually consider what you have in your report and tell us, so we have something to work with.
If the sections of the report are not what you would think of as too big for one of your pages then you might check all the sections for the following properties :
- Force New Page
- New Row Or Col
- Keep Together
This may help you find it anyway, but if not you really need to consider sharing the information of what you're working with if you expect help.
