basic Flex to Coldfusion cfstoredproc question

Just starting this ride ...

<cfstoredproc procedure="gmac.sel_smmry_by_mnth( 3,'2001')" datasource="orcl"> called the Oracle proc correctly with the parms. I then attempted

<cfcomponent>
<cffunction name="getMasterQuery"
output="false"
access="remote">
<cfargument name="rptNum" required="true" type="Integer">
<cfargument name="yrInput" required="true" type="String">
returntype="query">
<cfstoredproc procedure="gmac.sel_smmry_by_mnth" datasource="orcl">
<cfprocresult
name="qSummary">
<cfprocparam type="in"
cfsqltype="CF_SQL_INTEGER"
value = rptNum>
<cfprocparam type="in"
cfsqltype="CF_SQL_VARCHAR"
value = yrInput>
</cfstoredproc>
<cfreturn qSummary>
</cffunction>
</cfcomponent>

with the Flex call

this.dataManager.getMasterQuery(3,"2001"); I get a CFC error saying

The RPTNUM argument passed to the getMasterQuery function is not of type Integer. Not sure why I am getting this error - any help much appreciated,
