well you know that the variabled will be defined
so why not something like this
<cfscript>
function getValue()
{
if (isDefined(arguments[1]))
{return evaluate(arguments[1]));}
else
{
if (arrayLen(arguments) GT 1)
{return arguments[2];}
else
{return "";}
}
}
function replaceValues(inStr)
{
regExp = "%[^%]*%";
if (REFind(regExp, inStr))
{
do {
value = REFindNoCase(regExp,inStr,1,"TRUE");
inStr = replace(inStr,
Mid(inStr,value.pos[1],value.len[1]),
getValue(Mid(inStr,value.pos[2],value.len[2]),""),
"ALL"
);
}
while (REFindNoCase(regExp,inStr) NEQ 0);
}
}
</cfscript>
then just call
<cfoutput>#replaceValue(somestring)#</cfoutput>
Just something to think about

I've come in a bit late - but I know in one of my mailing list
sofwares I had a list of 'words' the user could enter, and they would
be evaluated into certain dynamic values.
I.e. '%Name%' would turn into the Person recieving the email's name...
'%From%' would display the From email.. etc.
So why not provide the user with a series of those? rather than open
yourself up to malicious code?
Hope I didn't miss someone suggesting this.
