Not valid/standard Oracle error.
It would be helpful if you followed Posting Guidelines - http://www.orafaq.com/forum/t/88153/0/
You can not shrink tablespace smaller than MAX(BLOCK_ID)

You have to first see which space you have in the tablespace files querying dba_free_space.
Then you can try to move the objects (alter table, alter index).
Ot you can export the objects, drop them from the tablespace, shrink the tablespace files and reimport the objects.
Take care of grants in this case.

There are other ways depending on many things like the availabkle space in the tablespace and in your disks.
