This is another approach I've used. Since there's a pattern to the
names, I just reReplace out the fields we're trying to count from
form.fieldNames and take the difference.
<cfset count = listLen(form.FieldNames) -
listLen(reReplaceNoCase(form.fieldNames, "headlined_[0-9]+,*", "",
"all"))>

You certainly do not need to do any of the below.
Items in the Form scope are treated like a structure. To get all the
fields, you can use structKeyList(). You can also use form.fieldnames,
a built in list of form fields.
To get the value, you use struct notation. Assume "key" is one form
field. The value can be retrieved like so:
form[key]
So all you need to do is loop through and examine fields that begin
with HEADLINEID.
