Create a demo Point using SINUSOID

I am trying to create a new tag using point builder, and point this tag to the built-in SINUSOID to generate random data. I used Point Builder in PI System Management Tools. I created a new point with the following attributes:

Name: JV_Test_Tag

Point class: classic

Point Type: float32

Display digits: -5

Point Source: demo

Source tag: SINUSOID

The tag is not getting any data. The current value is "Pt Created", and the Archive Editor does not show any archived data.

I am very new to the PI system, i have worked with other Historians in the past. I have a vCampus subscription and have searched high and low for just basic information on creating points and cannot seem to find that information.
