put objects in a group automatically by code

I have the following question. Maybe anyone has an idea. (sorry for my bad english).

I have to greate a lot of tables on a resettrigger. And I will put all this tables in a group by code. Later in the simulation I have to delete this group.

So, my idea is, fist I greate a group and everytime I greate a table I will put this table in the group. Please look the following code:

//great a group
treenode t_group = node("/Tools/Groups",model());
nodeinsertinto(t_group);
setnodename(last(t_group), "Tables");
treenode t_tables = node("/Tools/Groups/Tables",model());

//reference to to tabel nr. 1
treenode t_table = node("/Tools/GlobalTables/table_nr_1",model());

//insert table nr.1 in group
nodeinsertinto(t_tables);
nodeadddata(last(t_tables), DATATYPE_NUMBER);
setnodenum(last(t_tables), tonum(t_table)); // here is the problem! not the right code I thing!

My question: What is wrong with the last codeline?

Thanks for your help!!

If you want the Groups to conform to the Group structure you'll need to create couplings. I'll post a library with some commands that makes this easy in a few minutes.

This library installs some user commands. You get compile errors when it loads - that's a quirk you don't need to worry about.

very helpful in Flexsim R 6.0.2 - Thanks
