<cffeed> error on live server

I am getting the following error message from the <cffeed> tag on my live server (everything works perfectly on the local testing server).

"There is a problem in the column mappings specified in the columnMap structure.  The query attribute input does not contain any column by the name of strTitle."

Here is my code.

<cfset columnMapStruct = StructNew()>

<cfset columnMapStruct.title = "strTitle">

<cfset columnMapStruct.rsslink = "rsslink">

The problem is, I am using this database column in other queries on other pages in this site, with no problems.  In fact I copied/pasted the bd query from another page that is working fine.

Has anyone else encountered this?

Thanks.
