The last argument to proto_tree_add_uint() is not a Boolean specifying the byte order, it's the actual integral value to put into the tree.  The last argument to proto_tree_add_item() is a Boolean specifying the byte order.

For the interface count, you want

                       proto_tree_add_uint(helen_sub_tree, hf_helen_interface_count, tvb, offset, 1, interfacecount);

For status and cpu % used, you probably want to use proto_tree_add_item().

You want proto_tree_add_item() there, too.
