Disappearing data

I have an Update query to update a MySQL database. Everything seems to work fine except one form field..."bulbDesc". When I enter data into this field, which is longText type in MySQL, it disappears. Meaning when I go back to my view page, the bulbDesc in that particular record is blank. like I never entered any data. Here is my Update query code.

<cfparam name="URL.id" default="1">
<cfset CurrentPage=GetFileFromPath(GetBaseTemplatePath())>
<cfif IsDefined("FORM.MM_UpdateRecord") AND FORM.MM_UpdateRecord EQ "form1">

SELECT *

WHERE bulbID=#URL.id#
</cfquery>

It seems I can change or update every field except the #FORM.bulbDesc# field. I'm sure it's something simple I'm overlooking! Any help would be greatly appreciated.
