You'll have to loop through the list & add them all up manually.

CFLib.org has a UDF that does this as well.

No need to loop
try this, it converts the List to an Array, and then gets the sum.


<cfset someList="1,2,3,4,5">
<cfset totalSum=ArraySum(ListToArray(variables.someList))>

<cfoutput>
#variables.totalSum#
</cfoutput>

A nice alternate approach! I'd be interested to see if the overhead of transforming a list into an array is more or less than the overhead of looping over the list...but unless the list is huge the difference would probably be neglegable.

no wrong ways
This thread reminds me of an article I came across a while back on Fusion Authority

http://www.fusionauthority.com/Arti.../ArticleID=4128

It just goes to show that everyone may have a different approach to solve the same problem.
