Looking to use a check box to set value of a text field

Question

I have 2 address fields 1 for billing and 1 for shipping I put a check box in to determine if the shipping address is the same.  Keeping it simple just want the shipping address to check if the box is checked and if it is copy the information in the billing so they are the same and if it is not checked to leave it blank
any help with this would be appreciated.

Answer 1

I think I have it 90%there. I have no error now, it edits a
record fine, if you add the checkbox to the record it adds it, and
if you take it away, it does that. BUT now it will not add a new
record.
This is my code now for the update / insert
<cfif not IsDefined("FORM.admin")>
<cfset IsAdmin= 0>
<cfelse>
<cfset IsAdmin= 1>
</cfif>
<cfif isDefined("Form.RecordID")>
<cfquery datasource="#APPLICATION.dataSource#">
UPDATE user
SET user.Fname=<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.Fname#">,
user.Lname=<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.Lname#">,
user.userName=<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.userName#">,
user.password=<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.password#">,
user.email=<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.email#">,
user.admin =<cfqueryparam value="#IsAdmin#"
CFSQLType="CF_SQL_INTEGER">
WHERE ID =<cfqueryparam value="#form.RecordID#"
cfsqlType="CF_SQL_INTEGER">
</cfquery>
<cflocation url="indexUser.cfm?RecordID=#Form.RecordID#"
addtoken="no">
<cfelse>
<cfquery result="GetNewRecord"
datasource="#APPLICATION.dataSource#" dbtype="ODBC">
INSERT INTO user
(Fname, Lname, userName, password, email, admin)
VALUES (<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.Fname#">,
<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.Lname#">,
<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.userName#">,
<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.password#">,
<cfqueryparam cfsqltype="cf_sql_varchar"
value="#form.email#">,
<cfqueryparam value="#IsAdmin#"
CFSQLType="CF_SQL_INTEGER">)
</cfquery>
<cflocation url="indexUser.cfm">
</cfif>
Is there a better way to write this so it will work? I have
everything else working including the checkbox showing checked if
it is checked in the db, I believe this is my last hang up on a
checkbox.
Any ideas?
