DHTML hotspots don't work when linked from Framemaker

Question

I'm using Adobes Technical Communication Suite 4 on a 30-day trial to determine how well it will work for single-source publishing. I'm familiar with Robohelp (having used it for over a year) but have had almost no experience with Framemaker (and none with version 11, which is part of the suite).
Until now, we've been writing in Word and importing files into Robohelp. We use the Dynamic HTML features of Robohelp to create drop-down and expanding text (usually to provide the definition of a term). Word doesn't provide a way to create them, so it has to be done in Robohelp after import. However, with Framemaker, I should be able to create these features in FM have them appear in a linked RH file. There is a Framemaker menu to support their creation.
But when I attempt to do this, it doesn't work. The " text caption" (that the user clicks on to see the expanded or drop-down text) imports correctly into RH, but the expansion does not work. When clicking on the caption text in the HTML preview, the only thing that happens is that a single space appears where the drop-down text should be. The drop-down text itself remains invisible. (But I know it's there because I can find it in the HTML source code view.)
I am probably doing something wrong when I set this up in FM. Here is my procedure.
First, I type the text that will be clickable by the user to elicit the drop-down (this is what I presume Adode means by "text caption"). Then, in a new paragraph, I type the text that is intended to be displayed in the drop-down.
The instructions (for drop-down text) in the help say:
"Select the text or paragraph on which you want to place the drop-down text caption. "
So I select the "text caption" text.
"Select Adobe RoboHelp > Dynamic HTML Effects > Drop Down Caption"
I select that menu choice.
"Select the text that should appear as drop-down text in your online help page."
I select the next paragraph, which contains the drop-down text.
"Select Adobe RoboHelp > Dynamic HTML Effects > Drop Down Body"
I select that menu choice.
I save the file and then switch to Robohelp and update the linked file.
The "text caption" then appears in the RH file, but the drop-down text does not appear (except in the HTML source code).
What am I doing wrong?

Problem solved, through experimentation.
For the benefit of those who may experience this problem in the future: the secret is that there must be exactly one return (i.e. one press of the Enter key) between the "text caption" and the "drop-down text".
If the text caption and drop-down text are on the same line, it doesn't work (the coding for the text caption is disrupted) and if there is anything besides a return between them, it doesn't work (the drop-down text is not displayed).
