Question : How to use CFQUERY and CFSELECT multiple selection together?

I am trying to do a form where you can select certain employees involved in a project.  I can successfully pass these employees to the next page where their names are displayed, "name1, name2" like that.  


-------------------------
But, I cannot use names in my table.  They must be ID numbers.  I can convert the names to numbers ONLY if only one employee is selected from the previous page.  When I have more than one, nothing happens.


  SELECT UserID
  FROM check
  WHERE name='#FORM.Involvement#'


The code above is how I convert them.  How do I get it so that I can output the numbers AND pass these numbers to another page so I can insert them into a table?  

Also, after passing these numbers, how do you insert these multiple numbers?  Do I use a loop or is there an automatic piece of code to use.  
How do I calculate the number of names that were selected?  

Thanks for your time.  I truly appreciate it!

Answer : How to use CFQUERY and CFSELECT multiple selection together?

Here is what you need:

-----------------------------

      select UserID, Name from check


-----------------------------
Note that VALUE should contain UserID and DISPLAY - Name.

Now how you would retrieve selected rows:

-----------------------------

  SELECT UserID, Name
  FROM check
  WHERE UserID in (#form.Involvement#)


-----------------------------
That's it.
