Can't scroll down on excel

[no.18shirt]

I'm trying to scroll down my work sheet but it's not letting me. Every time I move the scroll bar down the page it just keeps showing me the same part of the sheet eg cells 1-30 when I want to see all the way down to the bottom. I have some 20,000 lines I need to scroll through but I can't see all of them. To add to this, I keep having lines hide between other lines so theres a big gap like going from line 120 to line 4000 and I have to manually unhide them every time to see them and its annoying.

Does anyone know how to fix my problems?

"View / Freeze Panes / Unfreeze Panes" should do the trick.
