I am trying to import a field that contains a list of locations.

When I add a LookUp field to the form none of the fields in my other form are displayed (they are all drop down single select).

Just to check, I tried using LookUp to create a relationship with another form, the only fields that displayed as an option to import were the single line fields.

Why aren't the drop-down fields available?

In the Creating a Relationship tutorial the example given uses drop-downs???
