I don't think that function makes sense for this. Perhaps your sql should use IN operator because of your cs values. However, I think you'll have to do this in code because each value would have to be delimited with single quotes, unless maybe you're willing to type those around every value you enter. If you try to do it in a stored query, you'll need a form that has a control containing the cs values, but again, everything needs to be delimited one way or the other - by your typing, or by code.
The more we hear silence, the more we begin to think about our value in this universe.
