insert into table by looping over structure - coldfusion

Question

I am trying to insert into the code but it is inserting value in every row, rather than question value in question and answer value in answer:
<cfset StructDelete(structform,'title')>
<cfset StructDelete(structform,'mode')>
<cfset StructDelete(structform,'formsubmission')>
<cfset StructDelete(structform,'file_upload')>
<cfset StructDelete(structform,'czContainer_czMore_txtCount')>
<CFSET StructDelete(structform,'action')>
<CFLOOP collection="#structform#" index="whichPair">
<cfset Questions = "question" & structform[whichPair]>
<cfset answer = "answer" & structform[whichpair]>
<cfquery name="insertData" datasource="aas">
insert into faqsquestions(question,answer,createdon,faqID)
values(<cfqueryparam cfsqltype="cf_sql_varchar" value="#Right(questions, Len(questions)-8)#">,
<cfqueryparam cfsqltype="cf_sql_longvarchar" value="#Right(answer, Len(answer)-8)#">,
<cfqueryparam cfsqltype="cf_sql_date" value="#CreateODBCDate(now())#">,
<cfqueryparam cfsqltype="cf_sql_integer" value="#getLastID#">)
</cfquery>
</CFLOOP>
can anyone tell what i am doing wrong here, i know i am using question as a static value just inside the loop as cfset and doing a right to remove that question variable which makes no sense but i will remove it when i am finished fixing my code

That's the wrong type of loop for what you're trying to do. The reason is a structure loop iterates once - for each field. When what you want is to loop once - for each pair of fields.
A simple option is add a hidden field to your form, containing the total number of pairs.
<input type="hidden" name="NumberOfQuestions" value="#TheTotalNumberHere#">
Then use the total number with a from and to loop. On each iteration, extract the current value of the question and answer fields, and use them in your query:
<cfloop from="1" to="#FORM.NumberOfQuestions#" index="pairNum">
<cfset question = FORM["question"& pairNum]>
<cfset answer = FORM["answer"& pairNum]>
<cfquery ...>
INSERT INTO faqsQuestions(question,answer,createdon,faqID)
VALUES (
<cfqueryparam cfsqltype="cf_sql_varchar" value="#question#">
, <cfqueryparam cfsqltype="cf_sql_longvarchar" value="#answer#">
, <cfqueryparam cfsqltype="cf_sql_date" value="#now()#">
, <cfqueryparam cfsqltype="cf_sql_integer" value="#getLastID#">
)
</cfquery>
</cfloop>
