Thane,
No need to have a separate "CommitWrite" variable. Just do this:
<cftransaction><!--- Begin is implied --->
<cftry>
<cfloop>
...DB Inserts here...
</cfloop>
<cfcatch type="Database">
<cftransaction action="rollback"/>
</cfcatch>
</cftry>
</cftransaction><!--- Commit is implied --->
Provided you want all inserts to be performed or none at all...otherwise
you need to adjust where the loop is etc.

Subject: CFTransaction and looping through multiple inserts
I'm entering a series of answers into a table, so I have a loop like
this:
<cfloop index="QuestionID" list="#Form.SurveyQuestionIDList#">
<!--- Get the answer. --->
<CFSET NumericAnswer=Form["Answer"&QuestionID]>
<!--- Run the query. --->
<cfquery datasource="#Datasource#" name="InsertSurveyAnswers">
INSERT INTO SurveyAnswers(QuestionID,
SurveySubjectID,
NumericAnswer, SurveyDate)
VALUES (#QuestionID#, #Form.SubjectID#,
#NumericAnswer#, #Form.DateSurveyEntered#)
</cfquery>
</CFLOOP>
If I want to use CFTransaction, would I set it up like this?
<CFSET CommitWrite=True>
<cftransaction action=begin>
<cftry>
<cfloop index="QuestionID" list="#Form.SurveyQuestionIDList#">
<!--- Get the answer. --->
<CFSET NumericAnswer=Form["Answer"&QuestionID]>
<!--- Run the query. --->
<cfquery datasource="#Datasource#"
name="InsertSurveyAnswers">
INSERT INTO SurveyAnswers(QuestionID,
SurveySubjectID, NumericAnswer,
SurveyDate)
VALUES (#QuestionID#, #Form.SubjectID#,
#NumericAnswer#, #Form.DateSurveyEntered#)
</cfquery>
</CFLOOP>
<cfcatch type='database'>
<cfset CommitWrite=FALSE>
</cfcatch>
</cftry>
<cfif CommitWrite is 'TRUE'>
<cftransaction action='Commit'>
<cfelse>
<cftransaction action='Rollback'>
</cfif>
</cftransaction>
Or like this?
<CFSET CommitWrite=True>
<cftransaction action=begin>
<cfloop index="QuestionID" list="#Form.SurveyQuestionIDList#">
<!--- Get the answer. --->
<CFSET NumericAnswer=Form["Answer"&QuestionID]>
<!--- Run the query. --->
<cftry>
<cfquery datasource="#Datasource#"
name="InsertSurveyAnswers">
INSERT INTO SurveyAnswers(QuestionID,
SurveySubjectID, NumericAnswer,
SurveyDate)
VALUES (#QuestionID#, #Form.SubjectID#,
#NumericAnswer#, #Form.DateSurveyEntered#)
</cfquery>
<cfcatch type='database'>
<cfset CommitWrite=FALSE>
</cfcatch>
</cftry>
</CFLOOP>
<cfif CommitWrite is 'TRUE'>
<cftransaction action='Commit'>
<cfelse>
<cftransaction action='Rollback'>
</cfif>
</cftransaction>
Or can CFTransaction be used in this situation?
