Instead of using a two-dimensional array, why not just use a structure?
At the beginning of your page, you could do this:
<cfset formErrorFields = structNew()>
Then, if a given field (say, firstname was blank) had something wrong
with it, do:
<cfif not len(trim(form.firstname))>
<cfset formErrorFields.firstname = "Please enter a first name.">
</cfif>
Then, in your form:
<cfinput type="text" name="firstname" required="true" message="Please
enter a first name"><br>
<cfif structKeyExists(formErrorFields, firstname)>
<cfoutput>#formErrorfFields.firstname#</cfoutput>
</cfif>
Granted, this limits you to only being able to have one thing wrong
with each field at a time, but there's no reason each element couldn't
be an array containing multiple error messages per field.

I've worked out a way using a two dimensional array
that contains the error message in the first dimension and set the
second dimension in the row to "Yes" if there is an error found.
Formfield 1 message is ErrorMessage[1][1] and ErrorMessage[1][2] is set to
"Yes" or "No".
(No by default)
Formfield 2 message is ErrorMessage[2][1], etc...
None of this is dynamic, just hard coded.
I just validate each form field and if there is a problem, set
ErrorMessage[1][1]
to hold whatever message is appropriate for the field and ErrorMessage[1][2]
to "Yes".
Then, there is a row just above each form field and its title which will
display
it's contents, ErrorMessage[1][1], etc., if ErrorMessage[1][2] has been set
to "Yes."
Now, all problems can be addressed at once, instead of one at a time...much
better!
For long forms, and as a standard of practice for all forms, I'll trigger a
message at the
top of the form which states that there are errors in the form input, and to
please check
your entries and correct as necessary.
Works great so far!
And Dick...even colorblind folks should be able to tell when a light-colored
background field
with dark text is changed to a dark-colored background with light
text...right?

I think you want to do both -- a list of errors and highlighted
fields-- maybe highlight by default and a popup, on demand, that lists
all the errors ( especially useful if the user has to scroll the
screen)
FWIW, there are a lot of color-blind users who surf the web-- at least
that's what I have been told!
