Error when inserting more than 500 characters

Question

Hello all,
I am not sure if I should be posting here or in the Flex
Forum, so I apologize ahead of time if I am in the wrong place.
I am Using a Flex frontend and a ColdFusion backend to edit
data in a simple Access Database (for testing). I have a ColdFusion
CFC on the backend that handles everything just fine until I enter
in more than 500 characters (Actually 510) into my text area and
then I get the error "Unable to invoke CFC - Error Executing
Database Query.". Now you might be saying that either the database
field is not set to handle that many characters or the CFC is
restricting more than 500 characters, but they are not. The
database field is set to "memo" and the maxlength in the CFC is set
to 5000. I am wondering if has something to do with Access
databases I do not know because I don't use them that often.
I have tested this over and over and it only throws the error
if I exceed 510 characters in the Flex TextArea.
Any thoughts are appreciated.
The CFC code is below I didn't add the MXML because I figured
there was nothing special about the TextArea block:

Very strange as to why this worked but just in case someone
else has the same problem here is how I got it to work.
I just changed this line:
rss_copy = <cfqueryparam value="#arguments.rss_copy_edit#"
cfsqltype="cf_sql_varchar" maxlength="5000">
to this:
rss_copy = '#arguments.rss_copy_edit#"'
and it worked just fine.
