Doing a test on a cfm email form. When filled in form is received email lists all fields as "left b

A newbie--trying to edit last year's form for this year. When filled in test form is sent--email lists fields and indicates each is "left blank". In the code I see an entry for each field that reads: <cfset xxxxx ="left blank"> is there a connection?. ie,

<cfif IsDefined('Form.Book_Evaluation')>

<cfset Book_Evaluation=REReplaceNoCase(#Form.Book_Evaluation#, "<[^>]*>", "" , "ALL" )>

<cfelse>

<cfset Book_Evaluation="left blank">

</cfif>

Thanks.
