How are you attempting to do this?

[Hagar Delest]

What command/menu/toolbar button do you use?

I'm not using any command I just go up to where it says font si and i change it that way

[Hagar Delest]

Are yo usure you don't mix the icons between font size and superscript/subscript?
If you select your text, go to the font size field in the toolbar (the one with a value) and change that value, what happens?
Can you post a screenshot of the toolbar command you are using?

[RoryOF]

For that to work, you have to select a section of text and then change the size in the toolbar. But this is Direct Formatting; you should be using Styles.
