duplicate value

[newbby]

All,
I have a variable that holds a comma delimited list of upto 5 numbers.How can I check that the numbers are not duplicated.
eg: the below is a good set
<cfset varMyNumbers = "12,43,55,76,44">
the below is not a good set
<cfset varMyNumbers = "12,43,55,76,43"> (43 is duplicated)
Thanks

<CFSET ListHasDupes="no">
<CFLOOP INDEX="i" FROM="1"
TO="#ListLen(varMyNumbers)#">
<CFSET item=ListGetAt(varMyNumbers,i)>
<CFIF ListValueCount(varMyNumbers,item) GT 1>
<CFSET ListHasDupes="yes">
<CFBREAK>
</CFIF>
</CFLOOP>
