Lua code problems

[Christian9]

So I'm working on a australia mod (aussie) and I'm trying to make a brebong (cassowary plum) tree for taming cassowarys. i based it off of the default tree api and at this string of code

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_abm({
   nodenames = {"aussie:brebongsapling"},
   interval = 10,
   chance = 50,
   action = function(pos, node)
      if not default.can_grow(pos) then
         return
                end
      local mapgen = minetest.get_mapgen_params().mgname
      if node.name == "aussie:brebongsapling" then
         minetest.log("action", "A sapling grows into a Brebong tree at "..
            minetest.pos_to_string(pos))
         if mapgen == "v6" then
            default.grow_tree(pos, random(1, 4) == 1)
         else
            default.grow_new_brebong_tree(pos)
      end
   end

It gives me this error

You forgot an end after the if/else

1 more thing, how do make a tree have fruit?

You might be intrested in my trees_lib mod. It allows you to easily add new trees. And if you intend to use the function (or schematic) used by existing trees, it won't be much extra work.
