Hi All,

After nearly an hour of screaming, I discovered the source to a recent issue.
There is a bug in GetWordNum(). If the string being searched begins with the delimiter, and you are requesting the first word, the function will return the Second word in the list.
? GetWordNum( "1,2,3", 1, ",")                     && returns "1"
? GetWordNum( ",2,3", 1, ",")                       && returns "2"
? GetWordNum( ",,3", 1, ",")                         && returns "3"
