This is not the case:
IsDefined is one of those 'funny' tags the proper syntax for checking the
existence of a variable FORM.FirstName is:
IsDefined("FORM.FirstName")
Also #'s are note required inside of most other tags so the following is
syntactically correct:
<cfif FORM.FirstName IS "Sean">
...
</cfif>
Use #'s to interpolate the variable (get at the value not the name). That's
why IsDefined is unusual, you are looking for the presence of a variable
_name_ in the symbol table, if you put #'s in there you'll be looking for
the presence of whatever FORM.FirstName's value is in the symbol table (if
FORM.FirstName is Bob, then IsDefined("#FORM.FieldName#") will look in the
symbol table for a variable named "BOB")
Inside of tags (and outside of quotes) CF interpolates the value for you so
you can do things like:
<cfif flag> <!--- True if flag is "YES" or 1 false if Flag is NO or
zero --->
<cfif Age GTE 21>
But if you have a variable called ColorList and ColorList="red,green,blue"
and you want to loop over that list, you'll need to use the #'s in the
list="" because you want to loop over the value contained in the variable
named colorList:
<cfloop list="#ColorList" index="thisColor">

Make a default value for the form, as: <cfparam name="form.req_just"
default="">
That should fix it for you.
