why it won't work?

i have the following ...

<cfquery datasource="#request.dsn#" name="qcheckforEncCCNum">
DECLARE @rC int
EXEC Check_Paym_For_Dup
@ccNum = <cfqueryparam cfsqltype="cf_sql_varchar" value="#request.params.liteEncryptCCNum#">,
@recCount = @rC OUTPUT
SELECT IsNull(@rc, 0) AS rCount
</cfquery>

when i do
<cfif qcheckforEncCCNum.rCount GT 0>
...
</cfif>

i receive variable rCount is not defined.

the query calls a stored proc which has an output var called @recCount which is either 1 or 0.

why doesn't CF not like this?
thanks for the help in advance

You can't declare a T/SQL block within cfquery like that. You'll have to move all that into a T/SQL procedure and call it using EXEC or using the <cfstoredproc> tag.
