You should not call toString on items which are already strings. In some cases it will return something other than the item you are expecting.

Solution 1

Check the length first instead of assuming its length is 14 or more.

Java

if(sVal.length() >= 14) 
{
   sVal = sVal.substring(1, 14);
}

Good luck!

ps. are you sure you want to start at 1 instead of the first character in the string (at position 0)?
