Passing Parameters to SQL Query and Displaying Result

Question

The user enters a serial number in a text box and then pushes a button to get info about the serial number. I do this with two regions. The first region has the text box and the button. The second region is a Report type region and contains the following SQL:
select case
when "WARRANTYSTATUS"."OUTOFWARRANTYDATE" >= sysdate then
'Serial Number '||"WARRANTYSTATUS"."SERIALNUMBER"||' is in warranty.'
else
'Serial Number '||"WARRANTYSTATUS"."SERIALNUMBER"||' is out of warranty.'
end as "The result is:"
from "WARRANTYSTATUS"
where "WARRANTYSTATUS"."SERIALNUMBER" in (:P1_SERIALNUMBER)
For a single serial number of the form CU5-0799 every thing works. I am a little suprised this works because the SERIALNUMBER in the WARRANTYSTATUS table is of type varchar2 which means the serial number in the where clause must be surrounded by single quoties. Not sure where the single quoties are being added.
However, what I like to do is to enter more that one serial number, seperated by commas, in the same text box, and then the query return a result for each serial number. What I would like to enter is:
CU5-0799, CU5-07132, CU5-89345
The problem is this string of three serial numbers will needs to be have single quotes around each serial number at the level of the sql statement. So the question is how do I make this work?? Thanks for the help in advance.

Bob,
If you would change your OTN handle to something more mnemonically friendly, that would help us. Thanks.

Not true. Quotes are used for literals, not bind variables.
