Trying to Create a Stateless Form

I am trying to create a Stateless form and am getting an error. I am looking up a field from one form and then trying to have it display relating fields that can be updated and then saved back to the other form. The form I am looking up is called Players, The field is called PlayerName. The fields I am trying to display are Team, Position, Owner. I keep getting an error and am not sure what is wrong. Can anyone help?

The code I am using is ....

form Draft
{
    store data in zc = false

    Lookup_1
    (
        displayname = "PlayerName"
        type = picklist
        values = Players.PlayerName
        on user input
        {
            r = Players [PlayerName == input.Lookup_1];
            input.Team = r.Team;
            input.Position = r.Position;
            input.Owner = r.Owner;
        }


    )
    Team
    (
        type = text
    )

    Owner
    (
        type = picklist
        values = Owners.OwnerName
    )

    Position
    (
        type = text
    )

actions
    {
        update
        {
            type = button
            displayname = "Update"
            on click
            {
                r = Players [PlayerName == input.Lookup_1];
                r.Team = input.Team;
                r.Position = input.Position;
                r.Owner = input.Owner;
            }
        }
        reset
        {
            type = button
            displayname = "reset"
        }
    }
}
