previewbread and pagebreak use

[victorvu]

Hi everyone:

I am newbie on this and trying to use the previewbreak and pagebreak by following the tutorial youtube video, but ran into issue:

1) I try to use the previewbreak by clicking it to where I want, but it gave me the RED solid line, instead of code.

2) I do the same for the pagebreak and it gave me the double lines with a box below it, instead of code.

3) What did I do wrong here?

4) Please show me step by step. The video is simplified in the way that it is just for the one whom already knows stuff.
