You are better off doing this using VBA (in my opinion), but the following
should work
SELECT *
FROM subComponent
WHERE Instr(1,"," & [Enter Types] & ",", "," & TypeID & ",") > 0
If you want you could strip out any spaces by using the replace function
(Access 2000 SP3 or later) to take care of typing errors
SELECT *
FROM subComponent
WHERE Instr(1,"," & Replace([Enter Types]," ","") & ",", "," & TypeID & ",")
> 0
>I have a query that I want to parameterize so that I can display data
> for any number of selected `Types` of components. My query (abridged)
[quoted text clipped - 12 lines]
> Is there a way to do this using parameters or must I generate the
> querystring in code?
