Matching on from a list

HI,

say I have a list from an sql statement (results list)
this list contains 10 items

In another table, in one particular column - there is a match for one of these items from the initial list.

SO... this may be the list
_____________________
itemnumber
1
2
3
4
5
6
7
8
9
10
----------

in the other table there is a match...
but just for one item on that list.
____________________
othertablefield
11
13
14
3 <-- match
99
78
---------

How do I find that match with my sql statement?SELECT [Othertablefield] FROM Table2 WHERE [Othertablefield] NOT IN (SELECT [itemnumber] FROM Table1)

HTH
