Web Service Error

Hello Experts-

I am using the attached cfc as a web service.  When I pass this single argument,
<cfinvoke
   method="landingPageAssets"
   returnvariable="CampaignInfo"
   webservice="http://admin.keywordconnects.com/webServices/ionCampaignDataDEV.cfc?wsdl">

   <cfinvokeargument name="cid" value="6">
   <!---  
    <cfinvokeargument name="ccid" value="1014684">
--->
 
      
</cfinvoke>

Everything works fine and I receive the XML packet back.  When I add other argument that is commented out in the code above, I get the following error message....

"Web service operation landingPageAssets with parameters {ccid={1014684},cid={6}} cannot be found."

Can someone tell me what I am doing wrong here?  Any help would be appreciated.  I've attached the cfc below...

Thanks
Nick
