How to Merge Databases?

I have two tables (same DB format) that I'd like to merge.
One table has the format of several colums:
ID, AlphaCol, BetaCol, GammaCol
The other has different columns:
ID, Foo, Bar, Baz
The ID colum in both are what ties the separate tables together.
I started out the process with the following command:
create table combinedtable select * from firsttable;
This created combinedtable with the columns ID, AlphaCol, BetaCol, GammaCol. Everything's cool so far.
Then, I thought I could do a command like:
insert into combinedtable select secondtable.Foo, secondtable.Bar, secondtable.Baz from secondtable, combinedtable where combinedtable.ID = secondtable.ID;
When I try this, however, I consistently get the error:
Error 1136 (21S01): Column doesn't match value count at row 1.
So, I'm missing something basic, but I didn't think this would be that difficult. What am I doing wrong?
