RSS feed – bgcolor error, feed not displayed

We are using ColdFusion to create a printable calendar page using the RSS feed from EM.

Events are reoccurring week to week. The weeks for June load perfectly, but starting on July 1st an error message for a specific recurring event (zumba) and the category color for that event is displayed on the page:

Error Occurred While Processing Request
Variable BGCOLOR is undefined.

150 : <cfelseif title CONTAINS ‘zumba’><cfset bgcolor = “13448c”>
151 : </cfif>
152 : <div style=”color: white; background-color: ###bgcolor#; width: 80px; height: 48px; position: absolute; left: #distanceleft#px; top: #distancetop#px; overflow: hidden;”>#TimeFormat(start, ‘short’)# – #TimeFormat(end, ‘short’)# #title#</div>
153 : </cfoutput>

I changed the category color in an effort to clear the error – but the error did not clear and the error message continues to displays the OLD category color not the new category color. It was #13448c but was changed to #153d77 last week.

The error displays for all July and August dates on the printable calendar, the webpage displaying the WP calendar looks perfect there are no errors on that page, its only when the RSS feed is used on the printable calendar page.
