Dave,
I set up all the sub variables before I call the mail tag with the loaded
variable. I worked through a solution that loops over each #cfvariable# and
#evaluates()# it:
<CFLOOP CONDITION="newpos GREATER THAN 0">
<cfset var_name="#mid(string,str.pos[1],str.len[1])#">
<cfset var_content="#Evaluate(var_name)#">
<cfset string=#Replace(string, var_name, var_content, "all")#>
<cfset str="#REFind("(##[A-Za-z][A-Za-z0-9_]*##)", string, newpos,
"true")#">
<cfset newpos=#str.pos[1]#+#str.len[1]#>
</cfloop>
There is actually a tag on the developer's exchange called cf_evaluate. It
uses a temporary file, though. The variable is stored in the temporary file
and then <cfinclud>ed. A similar concept would also work well for me. Just
keep all my mail messages in files and then include them.
Thanks for everyone's suggestions.
-Neil

Where is #first_name# coming from? Your query? IF so, make sure you're
referencing the query in the CFMAIL tag. Is it from a form? IF so, make it
#FORM.first_name#. Is it from another query? IF so, reference that query
in the output call.
#QueryName.first_name#
It works for me.

I've tried this before with no luck. I use place holders and do replaces
on those values.

Subject: substituting variables in a variable
I am trying to set up a mail system that can grab text from a database and
insert it into a mail message. I also need to customize the text of the
message (e.g. Dear #first_name# evaluates to Dear John). The problem arises
when I insert the mail text variable into the <cfmail> tag. The variables
that are contained in the text message are not evaluated.
<cfmail ..>
#mail_message#
</cfmail>
This will output "Dear #first_name#, ..."
How do I get the sub variable to be evaluated?
Thanks in advance,
Neil
