Well I must be doing something wrong because it doesn't work for me. I've read the Docs but still no luck.
I have tried to Link "Height" to both the existing "Height" predefined list AND a new list "MyHeight" created for testing.
Here's what I did after creating a "MyHeight" List with 2 Entries both with Value and LKey set.
Admin -> Builders -> Profile Fields -> Edit Profile -> Height
Changed Type to "Selector"
Changed "Possible Values" to "#Height" and "#MyHeight" (at different times for testing)
Default Value WILL NOT accept any input (neither Value nor LKey)- ends up with error symbol and "You entered an incorrect value". So I saved it without a default value.
When Editing Profile, the Height dropdown box contains either "#Height" or "#MyHeight" with no selection list options.
Have I missed something?
