For the test code I have used the account entity and from account entity I have choose "Preferred Day" and "Preferred Time" attributes because these attribute are already added when you create only organization which for trial for 30 day. You can see the selected attributes in the Image 1.
Next is the simple check of the Preferred Day text which user selected. I have set First option which is the Morning for the Monday , Afternoon for the Tuesday and Evening for the Wednesday , All option for the Thursday and first two option for the Friday. Here are some of the screen shots when user click the Monday there are only two option one is the empty and second is the Morning as you can see in the Image 2.
And in Image 3 you can see the all option when user select Thursday from the Preferred Day option set.
