need to find item from list

So your string would be:

65,66,67,68,69,70,71,72 ??

and you want to check if 69 is in it?

What version of CF are you using?

Bit more information would be helpful

i used this function

function listFindMissing(list) {
  var delim="-"; // list delimiter
  var arrToSearch="";
  var i=0;
  var j=0;    
  var returnList="";
  if(arrayLen(arguments) GTE 2) delim = arguments[2];
  arrToSearch=listToArray(list,delim);
  for(i=ArrayMin(arrToSearch);i LTE arrayMax(arrToSearch);i=i+1)
    for(j=1;j LTE arrayLen(arrToSearch);j=j+1)
      if(arrToSearch[j] EQ i)  break;
      else
        if (j EQ arrayLen(arrToSearch))
          returnList = listAppend(returnList,i,delim);
  return returnList;
}

but it is skipping the first and the last letter say

the values are 65-72

it shows me 66,67,68,69,70,71

i need the start and the end too of this

i am on cf 10

Thanks
