I am having issues getting the CSS selector to hook onto

Hello, I am having issues getting the CSS selector to hook onto a specific page element. I am selecting "tooltip" as the step type and have tried various combinations of ID, name, and class wrappers. No matter what I put, it looks like the plugin can't find the selector and defaults to nothing being displayed (aside from the "close" link at the top right).

One thing to note is that the HTML generated by wordpress contains id's, names, etc, but usually in the form of "class='class_name'", but doesn't specifically have "<class name="class_name">. Would this prevent the plugin from being able to identify the selector?
