I can't make a on click pop up using "Popup Domination" and wordpress theme

I have been going crazy over this.... I can't figure out where to put this code in the page, or what to change it to for a customizable button created from the word press theme. It doesnt seem there is anywhere to put that code. This is what they describe as the on click process

2 Here is what the code where the button is located looks like:

code from the wordpress theme, the text editor side

am I looking in the wrong place?
