Hi Carol,
"All I want to do now is put the plugin in a label for the student to
record or in an assignment with wieh instructions for the student to
record, he records himself answering the question. Then he submits it to
me." Students CANNOT make a PoodLL recording in a label because they do not have permission to create a label. When a teacher adds a PoodLL recording to a label, all the student can do is play it back.
In Moodle 2.7, for students to be able to make a PoodLL recording the way you want, then you want to set up an assignment so it's Submission types is Online PoodLL. This will then give students access to a PoodLL recorder, either audio or video depending on how you set the Poodle Rec. Type.

You will also need to be aware that some browsers will no longer allow flash. I do know that Firefox and Edge will work as I just tested with them, but Chrome failed.
Anyway, when students go to submit to the assignment, they will see a Flash setting and then the recorder.

There are other activities such as journal, forum, wiki, etc. in which students can type. In those cases, if you also have PoodLL Anywhere, or PoodLL Repository, they can submit recordings there.
As I mentioned before, the Read Aloud activity, might be a way to do what you want.
