You do not need the listlen(). That function just counts and returns the
number of items in a list. So what you have here would likely return '1'.
The inner function is correct. Try putting this on the forms action page so
you can see whats happening.
<cfoutput>
The value from the form is: #form.modelnumber# <BR>
The first item in the list is:#Listfirst(form.modelnumber)#<BR>
The second item in the list is:#listLast(form.modelnumber)#<BR>
</cfouptut>
Note, when you do this, #ListLen(Listfirst(form.modelnumber))#, you are
first (the inner function first) getting the first item in the list and
then (the outer function) counting the number of items in the list, which
is 1, the result of the inner function.
