How to loop through token values

I'm trying to create a simple loop that runs through a bunch of comma delimted values in a string and adds them together. What is the best way to do this?

Currently, my code looks something like this

<cfset basevalue = "0">
<cfset count = "1">
<cfset token = getToken(myString,count,",")>
<cfloop condition = "token NEQ NULL">
<cfset token = getToken(myString,count,",")>
<cfset basevalue = basevalue + token>
<cfset count = count + 1>
</cfloop>

This doesn't seem to be working. Any ideas?

Correct answer Sankalan

I think the correct syntax is index="token". If you have some other delimiter then,

<cfset thesum = 0>
<cfloop list="#mystring" index="token" delimiters="yourDelimiter ">
<cfset thesum = thesum + token>
</cfloop>

Oh, and, another thing. if your list is going to contain blank elements, like "1,2,3,,4,5", then it will be advisable to apply arrayToList() first.

This is equally simple.
<cfset thesum = 0>
<cfloop list="#mystring" item="token">
<cfset thesum = thesum + token>
</cfloop>

How does this know what the token is? By that I mean what the delimiter is?

The default delimiter is a comma, which you specified in your original post.

Here is a much simpler way to add the elements of a list:

<cfset arr=listToArray(myString)>
<cfset sum=arraySum(arr)>
