D7B4-BUG:Fields builder

1.Profile no show

2.Multiple Selector can collect data, but Selector doesn't work...

sorry! 1 is ok, but 2 can't show in edit profile page

Did you add the multiple selector to the Edit Profile page in the Profile Fields section?

yes.

Multiple Selector can display checked/selected, but Selector can't

I had no issue with this.
Make sure you follow the steps below and this should work.

Say you are adding a new field to your join page, edit profile, and view profile section.

1) Under the join section create your new field
2) Click the Edit Profile section
3) By default you will be on the Owner radio button, make sure you place your block where you want it.
4) Click the block, you will need to fill out the Caption again and description (the rest will still be in place)
5) Click the Admin radio button and place the same block where you want it.
6) Go to the View Profile and follow step 4.

Make sure you place the block in the General Info section...i just realized the misc section doesn't show lol....yeah, i'm a little slow sometimes.

Anyways hope this helps.

I have a question about adding a new block. I have set up a new predefined value, but I am wondering how to set it up in a new block.  I set the multiple selector, but cant insert the LKey.

You can't do it in a block, it has to be in the Fields builder.
Add your new predefined value, example:
Name: Dolphin Experience
value: Lots LKey: _Lots
value: Some LKey: _Some

And so forth.
You can than proceed with the steps in adding that to your profile and such by following the steps i showed above.
Once you view your profile you will see something like this:

_FieldCaption_DolphinUser_View:

If so, go to Settings --> Language Settings and add a new Key.
Paste in the _FiledCaption_DolphinUser_View in the Key Name than Dolphin User in the String for text field.
I'm quite sure there's a easier way, but that's what i know lol
Hopefully this will help you.
