Welcome in the forum, Jason.
The "Enable" input is shown only when you set the "Enable Mode" property to something different from "Software only".
Setting it to a logical "1" in your case was quite right.
You need to call the PWM_Start() API to enable the PWM. Setting property to "Software only" does not hinder the PWM to run.
When you still have got any problems, attach a workspace bundle (Creator->File->Create Workspace Bundle(minimal)) to your post, together with a note on what board you're running the project.
