CFML form will not insert into SQL Server 2014 database - sql-server

Question

Lucee 5.2, SQL Server 2014
I have a form that will not insert a new record into my SQL Server 2014 database.
I've studied this problem for a couple of days and nights and cannot figure out what is going on. I do not get an error message of any kind. I fill out the form, click the Submit button, and I am returned to a blank form. No record is inserted into the database table.
I have tested this abridged version of my code, below, but I still get the same result: no insert happens; and Lucee does not give me back any error message at all.

Answer 1

Your INSERT SQL is invalid. The list of values starts with a comma, that means Title must not be preceded by a comma.
The reason you don't see an error message is that the queries are wrapped into a <cftry>/<cfcatch> block. Within the <cfcatch> there is a <cfset variables.error = cfcatch.message>, though the actual error message is stored in cfcatch.detail. So it is not output.
