Problem with merging tables

[[EMAIL PROTECTED]]

I am getting the following error when I try to access a merged table:

This:

Select * from subjects_2;  or insert into subjects_2 (subj_id) values('10');

Returns:

ERROR 1017: Can't find file: 'subjects_2.MRG' (errno: 2)

Any Ideas what this means and how I can correct it.  I can access the two
tables merged by this table, just not the merged table itself.

Merging tables are new to me so take it easy on my novice self...

Thanks!
