T8SG Mixer complex page shift problem

When I am programming a mixer i nch5 as complex and want to shift from page 1 to page 2 I hit the right coursor button but nothing happens.
The field "page" stays on page 1.
Is this a softwarebug or am i doing something wrong? T
The button coursor right is functioning ok in other menus.
What I am trying to achive is a 3 way switch which gives me 3 fixed values; -100, 0 and 100 on ch 5.
Can I do that with 3 mixers instead and can you give me an example.

Sorry if my question is stupid but I am new in deviation software,

Thank you very much. Now I understand and it works.
I just need one thing more:

Is it possible to to program a timer only to run, when throttle is more than 10%?
