OrderBy records in SubForm

I have:

A F_Passages based in T_Passages.
And SubF_Chunks based in T_Chunks.

When change record in F_Passages the records in
SubF_Chunks, don't appear ordered.
In adition, the T_Chunks is ordered by Chunk in first
place of this table and One Passage to many Chunks.

Because the records in SubF_Chunks appear Record2,
Record1, Record3,...(disordered), how is possible to order
it in SubF_Chunks, please.

Thanks in advance.
