Session variable

I have the attached code for declaring and then using session values. However anytime I submit a form to the page with the session variables I am told that the varaibles are not defined, which should not be so since I have declared the said variables.

For example I am currently getting the following error: Element PRODUCTNAME is undefined in FORM. But as per my code, this has been defined. I have also tested the other elements and they are all being shown as undefined.

As always I aprreciate the help

    <cfif not isDefined("requestProfile")>
    Probably an error. It appears you wanted to do <cfif not isDefined("session.requestProfile")>.

    For example I am currently getting the following error: Element RODUCTNAME is undefined in FORM. But as per my code, this has been defined. I have also tested the other elements and they are all being shown as undefined.
    You probably haven't submitted a form or, if you did, some of the fields are not in it. To be sure, do something like this

    <cfif isdefined("form.productname")>
    <!--- Remember only details for product if customer (via email) already exists else remember all--->
    <cfif chkEmail.recordcount IS 0>
    <cfset Session.requestProfile.title = Form.title>
    <cfset Session.requestProfile.lastname = Form.lastname>
    <cfset Session.requestProfile.firstname = Form.firstname>
    <cfset Session.requestProfile.addrs1 = Form.addrs1>
    <cfset Session.requestProfile.addrs2 = Form.addrs2>
    <cfset Session.requestProfile.city = Form.city>
    <cfset Session.requestProfile.country = Form.country>
    <cfset Session.requestProfile.zipcode = Form.zipcode>
    <cfset Session.requestProfile.mobile= Form.mobile>
    <cfset Session.requestProfile.phone = Form.phone>
    <cfset Session.requestProfile.fax = Form.fax>
    </cfif>
    <cfset Session.requestProfile.productname = Form.productname>
    <cfset Session.requestProfile.productmodel = Form.productmodel>
    <cfset Session.requestProfile.producttype = Form.producttype>
    <cfset Session.requestProfile.productyear = Form.productyear>
    <cfset Session.requestProfile.productdescription = Form.productdescription>
    </cfif>

    Thanks, the code works. I am just a little confused as to why I have to check that one of the fields is defined(i.e <cfif isdefined("form.productname")> before my assignment of values will work. Basically ColdFusion is refusing to recognize
    form fields until one of them has been tested to check for existence.

    Suppose Coldfusion enters a page and encounters, for example, <cfset myVar = form.fieldVal>. If this is just the "first pass" of the page, and a form has not yet been submitted, Coldfusion will generate an error. There is no form scope yet, hence the need for <cfif isdefined("form.productname")>. In fact, you may use any form field for the test, e.g. <cfif isdefined("form.someOtherFormFieldName")>

    You've misread the error message. it's telling you thatt Form.ProductName is undefined not Session.ProductName.
    <cfif IsDefined("Form.ProductName")>
