Because you're allowing users to enter ranges, you will probably have to
loop over the input list and parse out the ranges, manually counting each
element. For example:
<CFPARAM NAME="FORM.numList" DEFAULT="">
<CFSET count = 0>
<CFLOOP LIST="#FORM.numList#" INDEX="currEle">
<CFIF Find("-", currEle) EQ 0>
<!--- not a rnage, increment by 1 --->
<CFSET count = count + 1>
<CFELSE>
<!--- range, determine range elements --->
<CFSET beginNum = Trim(GetToken(currEle, 1, "-"))>
<CFSET endNum = Trim(GetToken(currEle, 1, "-"))>
<CFSET count = count + (endNum - beginNum) + 1>
</CFIF>
</CFLOOP>
<CFOUTPUT>There were #count# numbers entered.</CFOUTPUT>
