Unfortunately it's messy...
<cfset numList = "1,2,5-9">
<cfset count = 0>
<cfloop list="#numList#" index="i">
<cfif i CONTAINS "-">
<cfset count = count + abs(val(i))>
<cfelse>
<cfset count = count + 1>
</cfif>
</cfloop>

Subject: parsing user input to get count
I have a text field that I allow users to input data as follows:
1,2,5-9
Basically it is a coma delmited list with a range. Whats the best way to
get a count... in this case I'd need to return 7
Thanks in advance...
